2010-09-23ppc4xx: Cleanup of PVR detection code in cpu.cStefan Roese
This patch cleans the PVR detection code in check_cpu() up a bit. Basically the strings are better seperated, resulting in an easier to understand and maintain code version. The #ifdef's couldn't be removed easily because of two reasons: - Some SoC revisions have the same PVR, so need a way to differentiate between those two SoC's. - In some case statements registers only available in this SoC variant are referenced. Instead I moved the CONFIG_440 #ifdef a bit, so that 405 platforms don't add this 440 detection code and vice versa. Resulting in this U-Boot image size change: 405EX (Kilauea): 408 bytes less 440EPx (Sequoia): 604 bytes less 460EX (Canyonlands): 564 bytes less Signed-off-by: Stefan Roese <sr@denx.de> Cc: Wolfgang Denk <wd@denx.de>
2010-09-23ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese
This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>
2010-09-23ppc4xx: Big header cleanup part 2, mostly PPC405 relatedStefan Roese
This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. As a part from this cleanup, the GPIO definitions for PPC405EP are corrected. The high and low parts of the registers (for example CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in the wrong order. This patch now fixes this issue by switching these xxxH and xxxL values. This brings the GPIO 405EP port in sync with all other PPC4xx ports. Signed-off-by: Stefan Roese <sr@denx.de>
2010-09-23ppc4xx: Big header cleanup, mostly PPC440 relatedStefan Roese
This patch starts a bit PPC4xx header cleanup. First patch mostly touches PPC440 files. A later patch will touch the PPC405 files as well. This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. Signed-off-by: Stefan Roese <sr@denx.de>

2010-09-03ppc4xx: Fix 440EPx bug in reconfigure_pll()Stefan Roese
This patch fixes a bug in reconfigure_pll(), where the detection of the current bootstrap option is wrong. The ICS bits where incorrectly shifted. This bug was found on the lwmon5 board, which uses bootstrap option H (I2C bootstrap EEPROM). Additionally a bit of code was moved into the if statement, since its only used after later on. No need to run this code all the time. Also, a few empty lines are added to make the code better readable.

2010-08-04Rename getenv_r() into getenv_f()Wolfgang Denk
While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>

2010-07-23ppc4xx: Add "ecctest" command to test/simulate ECC errorsStefan Roese
This patch adds the "ecctest" command to test and simulate ECC errors (single bit and/or double bit) while running from SDRAM. Currently only the IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT). This is done by copying and calling functions, modifying the SDRAM controller operation mode, in internal SRAM/OCM. For correctable ECC errors (single bit) only the status will be printed since the DDR2 controller doesn't provide the faulting address: => ecctest 1000000 1 Using address 01000000 for 1 bit ECC error injection ECC: Correctable error Uncorrectable ECC errors (double bit) will also display the faulting address: => ecctest 1000000 2 Using address 01000000 for 2 bit ECC error injection ECC: Uncorrectable error at 0x0001000000 To enable this "ecctest" function you need to define CONFIG_CMD_ECCTEST in the board config header.
