2011-04-28video: parse the video-mode environment variableTimur Tabi
Add function video_get_video_mode(), which parses the "video-mode" environment variable and returns each of its components. The format matches the video= command-line option used for Linux: video-mode=<driver>:<xres>x<yres>-<depth>@<freq><,option=string> <driver> The video driver, ignored by U-Boot <xres> The X resolution (in pixels) to use. <yres> The Y resolution (in pixels) to use. <depth> The color depth (in bits) to use. <freq> The frequency (in Hz) to use. <options> A comma-separated list of device-specific options Signed-off-by: Timur Tabi <timur@freescale.com>

2011-01-19mpc85xx: Enable unique mode registers and dynamic ODT for DDR3York Sun
Added fsl_ddr_get_version() function to for DDR3 to poll DDRC IP version (major, minor, errata) to determine if unique mode registers are available. If true, always use unique mode registers. Dynamic ODT is enabled if needed. The table is documented in doc/README.fsl-ddr. This function may also need to be extend for future other platforms if such a feature exists. Enable address parity and RCW by default for RDIMMs. Change default output driver impedance from 34 ohm to 40ohm.

2010-11-30Add board support for hawkboardSughosh Ganu
The patch adds basic board support for TI's OMAP-L138 based Hawkboard. This board is pretty similar to the da850 EVM. Support for nand and network access is added in this version. The following bootup procedure is used. At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand controllers and copies the second stage bootloader(nand_spl) to RAM. The secondary bootloader then copies u-boot from a predefined location in the nand flash to the RAM, and passes control to the u-boot image. Three config options are supported * hawkboard_config - Used to create the u-boot.bin. Tftp the u-boot.bin image to the RAM from u-boot, and flash to the nand flash at address 0xe0000. * hawkboard_nand_config - Used to generate the secondary bootloader(nand_spl) image. This creates an elf file u-boot-spl under nand_spl/. Create an AIS signed image using this file, and flash it to the nand flash at address 0x20000. The ais file should fit in one block. * hawkboard_uart_config - This is same as the first image, but with the TEXT_BASE as expected by the RBL(0xc1080000).

2010-11-19DA850 EVM: passing maximum clock rate information to kernelSekhar Nori
The TI DA850/OMAP-L138/AM18x EVM can be populated with devices having different maximum allowed CPU clock rating. The maximum clock the chip can support can only be determined from the label on the package (not software readable). Introduce a method to pass the maximum allowed clock rate information to kernel using ATAG_REVISION. The kernel uses this information to determine the maximum cpu clock rate reachable using cpufreq. Note that U-Boot itself does not set the CPU clock rate. The CPU clock is setup by a primary bootloader ("UBL"). The rate setup by UBL could be different from the maximum clock rate supported by the device. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

2010-10-29Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk
When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>

2010-10-22post/i2c: Add ability to ignore I2C devicesPeter Tyser
Add the ability to not report an I2C POST error for a set of given I2C addresses on bootup. This is useful for cases when a device may or may not be present, and neither case is considered an error. For example: - Some form factors such as XMC and Compact PCI Express have an I2C EEPROM whose address changes based on geographical address. Eg installed in one slot its EEPROM address is, 0x50, in another its 0x51, etc. This allows multiple devices to have their EEPROMs present on the same I2C bus. Thus the I2C devices present for an XMC or CPCIe card depend on if and where other cards are installed in the same system. - Some cards have optional I2C devices. Eg one hardware build configuration has different I2C devices than another and software can't determine if the optional device should be present or not. - Some cards have optional daughtercards with I2C devices on them. - I2C EEPROMs address range depends on their size. Its possible to support differently size EEPROMs by only probing the EEPROM's base address and ignoring the other addresses that are impacted by its size. A new CONFIG_SYS_POST_I2C_IGNORES define has been added which specifies a list of I2C addresses for the I2C POST to ignore.

2010-10-20Add memory test feature for mpc85xx POST.York Sun
The memory test is performed after DDR initialization when U-boot stills runs in flash and cache. On recent mpc85xx platforms, the total memory can be more than 2GB. To cover whole memory, it needs be mapped 2GB at a time using a sliding TLB window. After the testing, DDR is remapped with up to 2GB memory from the lowest address as normal. If memory test fails, DDR DIMM SPD and DDR controller registers are dumped for further debugging. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
