2011-05-26hw: Add Overo board supportoveroPeter Maydell
Add Gumstix Overo board definition (an OMAP3 based board). Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-05-26hw/9118.c: Implement active-low interrupt supportPeter Maydell
The 9118 ethernet controller interrupt line is active low unless the IRQ config register is programmed to set both the IRQ_POL (polarity: active-high) and IRQ_TYPE (type: push-pull) bits: implement support for inverting the irq output in other configurations. This also requires that we support setting the bits in the first place, and that we correctly preserve them across software reset. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-21Changelog.LINARO: Update for 2011.04-1 releasePeter Maydell
2011-04-21lm32: fix build breakage due to uninitialized variable 'r'Peter Maydell
gcc 4.5.2 correctly complains that r is potentially uninitialized in this function. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-04-20Add a note that SPARC compile failures were fixed in 2011.04Peter Maydell
2011-04-19linux-user/arm/nwfpe: rename REG_PC to ARM_REG_PCPeter Maydell
The REG_PC constant used in the ARM nwfpe code is fine in the kernel but when used in qemu can clash with a definition in the host system include files (in particular on Ubuntu Lucid SPARC, including signal.h will define a REG_PC). Rename the constant to avoid this issue. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-19configure: Make epoll_create1 test work around SPARC glibc bugPeter Maydell
Work around a SPARC glibc bug which caused the epoll_create1 configure test to wrongly claim that the function was present. Some versions of SPARC glibc provided the function in the library but didn't declare it in the include file; the result is that gcc warns about an implicit declaration but a link succeeds. So we build the configure test with -Werror to avoid the test passing but then a -Werror qemu build failing. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-18Changelog.LINARO: Update for 2011.04-0Peter Maydell
Update the Linaro changelog for the 2011.04-0 release.
2011-04-13linux-user: Dummy implementation of prlimit64 to avoid warningsPeter Maydell
Special-case prlimit64 to return ENOSYS without printing the default "unhandled syscall" warning; this is a new syscall so anything trying to use it will have a fallback case, and the warning can result in a lot of noise (for instance, when running apt under qemu). This will be replaced with a proper implementation later. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13hw/omap_uart.c: Forbid extended MCR bit writes unless in enhanced modePeter Maydell
The OMAP UART defines new functions for MCR bits 5 and 6; these can only be written if the appropriate bit is set in the EFR register. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13hw/omap_uart.c: Refactor register access mode testsPeter Maydell
The OMAP UART provides different views of the registers depending on the access mode specified by the value in the LCR register. Refactor this to use an enumeration indicating the current mode rather than doing checks of the cache LCR value everywhere. Similarly, pull out into a function the check of whether registers 0x18/0x1c are in TCR/TLR mode. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13hw/omap_uart.c: Unconditionally enable non-16550 extensionsPeter Maydell
Uncondionally enable the OMAP UART modelling of the extensions over plain 16550A, instead of having them guarded by #ifdefs and disabled by default. Newer Linux kernels have an OMAP specific serial driver which relies on these being implemented. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13hw/omap3_mmc.c: Set TC status bit for R1b no-data commandsPeter Maydell
We emulate MMC commands with response type R1b and no data transfer instantaneously, so we must set the TC bit as well as the CC bit, to indicate that the "busy" period has ended. Without this fix the Linux driver will hang waiting for a TC interrupt that never happens when it tries to do a block erase. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13hw/omap3_mmc.c: Use symbolic constants for status register bitsPeter Maydell
Use symbolic constants rather than hardcoded numeric values for the OMAP3 MMC status register bits, to improve readability. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13pc-bios: delete binary blobsPeter Maydell
Delete the binary blobs in pc-bios where we don't have corresponding source in this git repository. This avoids problems with potentially redistributing GPLed binaries without source; we don't need any of them for ARM targets anyway. See: https://bugs.launchpad.net/qemu-linaro/+bug/709965 Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13configure, Makefile: don't require binary blobs to be presentPeter Maydell
In configure and Makefile, don't insist on the presence of the binary blobs in pc-bios, but silently skip any which aren't present. This allows us to delete them from the repository without causing build failures. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13Add a Changelog.LINAROPeter Maydell
Add a Changelog.LINARO to document the changes we make between qemu-linaro releases. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13Add Linaro versioningPeter Maydell
Add a VERSION.LINARO file so it's clear that tarball releases are from Linaro rather than upstream, and make the configure pkgversion default to the Linaro version number so that the -version option says Linaro too (even if the user built from the tarball without specifying -pkgversion to configure). Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13make omap3_mmc status register directly accessibleJuha Riihimäki
Changes in the status register are immediately in effect, i.e. the guest does not need to read the status register first before writing changes to it. This change may cause problems if guest code does not handle properly the case where transfers get completed immediately when initiated. Signed-off-by: Juha Riihimäki <juha.riihimaki@nokia.com>
2011-04-13hw/omap3_boot.c: don't override image header detection for MMC imagesPeter Maydell
Remove code which was erroneously overriding the detection of a CHSETUP header in an OMAP boot image loaded from an MMC card. Newer versions of x-loader create MLO files which include this CHSETUP header, and if we don't correctly skip over it to the actual code then they won't boot. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13hw/twl4030: Add dummy implementation of BCISIHCTRLPeter Maydell
Add a dummy implementation of the BCISIHCTRL register to the twl4030. BCI interrupts are not currently implemented, but recent Linux kernels try to write to this register so we need to at least support reading and writing the register, so the kernel will boot. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13hw/arm_boot.c: move initrd load address up to accommodate large kernelsPeter Maydell
Newer kernels are large enough that they can overlap the address qemu places the initrd. Move the initrd up so that there is enough space for the kernel again. Unfortunately it's not possible to automatically determine the size of the kernel if it is compressed, so this is the best we can do. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13audio: fix integer overflow expressionPeter Maydell
(part of a commit by Juha)
2011-04-13sd: Don't complain about SDIO commands CMD52/CMD53Peter Maydell
The SDIO specification introduces new commands 52 and 53. Handle as illegal command but do not complain on stderr, as SDIO-aware OSes may legitimately use these in their probing for presence of an SDIO card. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13omap_gpmc: Implement prefetch enginePeter Maydell
This commit implements the prefetch engine feature of the GPMC which can be used for NAND devices. This includes both interrupt driven and DMA-filling modes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2011-04-13omap_gpmc: pull prefetch engine data into sub-structPeter Maydell
Refactor the gpmc state structure so items relating to the prefetch engine are in their own sub-struct and have more useful names. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13omap_gpmc: fix handling of FIFOTHRESHOLDSTATUS bitPeter Maydell
The OMAP3 TRM is inconsistent about whether the GPMC FIFOTHRESHOLDSTATUS bit should be set when FIFOPOINTER > FIFOTHRESHOLD or when it is >= FIFOTHRESHOLD. Apparently the underlying functional spec from which the TRM was created states that the behaviour is ">=", and this also makes more conceptual sense. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13omap_gpmc: Wire up the GPMC IRQ correctlyPeter Maydell
The omap_gpmc wasn't actually wiring up its IRQ, so anything that provoked an interrupt would be using uninitialised data for its IRQ number. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13omap_gpmc: GPMC_IRQSTATUS is write-one-to-clearPeter Maydell
Fix a bug in the handling of writes to GPMC_IRQSTATUS: it behaves as "write one to clear, writing zero is ignored". Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2011-04-13omap_gpmc: Refactor omap_gpmc_cs_map and omap_gpmc_cs_unmap()Peter Maydell
Refactor omap_gpmc_cs_map and omap_gpmc_cs_unmap() so that: * they take the top level struct and a chipselect rather than the cs_file struct * the 'is CSVALID set?' check is done by them rather than by all callers Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2011-04-13omap_uart: allow 32-bit register accessJonathan Daugherty
While on some OMAP models 16-bit or 32-bit access to the UART registers can cause data corruption, modelling the faulty behavior is mostly useless and even the current implementation of it is inaccurate. Since there is software that does 32-bit access to the registers it should be allowed. Signed-off-by: Juha Riihimäki <juha.riihimaki@nokia.com>
2011-04-13omap_gpmc: map NAND devices into memory correctly.Peter Maydell
The OMAP GPMC is supposed to map NAND memory devices into its address space so that any access behaves like an access to the appropriate GPMC_NAND_DATA_i register; implement this behaviour in the model. Signed-off-by: Juha Riihimäki <juha.riihimaki@nokia.com>
