2011-05-12Fix incorrect use of getenv() before relocationWolfgang Denk
A large number of boards incorrectly used getenv() in their board init code running before relocation. In some cases this caused U-Boot to hang when certain environment variables grew too long. Fix the code to use getenv_r().

2010-12-17ppc4xx: t3corp: Add support for the Xilinx DS617 flash chipStefan Roese
The t3corp board has an Xilinx DS617 flash chip connected to the onboard FPGA. This patch adds support for these chips. Board specific flash accessor functions are needed, since the chips can only be read correctly in 16bit mode. Additionally the FPGA chip-selects are configured for device-paced transfers (ready is enabled). Signed-off-by: Stefan Roese <sr@denx.de>

2010-09-23ppc4xx: Move ppc4xx headers to powerpc include directoryStefan Roese
This patch moves some ppc4xx related headers from the common include directory (include/) to the powerpc specific one (arch/powerpc/include/asm/). This way to common include directory is not so cluttered with files. Signed-off-by: Stefan Roese <sr@denx.de>
2010-07-23ppc4xx: T3CORP fixes and updatesStefan Roese
This patch fixes some problems for the T3CORP board. Here the list of the changes: - Add 600-67 and 677 CPU frequency setting to chip_config command - Define CONFIG_DDR_RFDC_FIXED on t3corp: While using the "normal" auto calibration code, sometimes values for RFDC were picked (>= T3) that resulted in a non-working U-Boot (hang upon relocation, while running from SDRAM). With this optimized RFDC value we can force this register and use the auto-calibration code to setup the remaining calibration registers. - Increase sizes of FPGA chips selects - EBC timing updated OEN=3 for 66 MHz EBC speed - Change ext. IRQ2 setup to level-low active - Enable CONFIG_SYS_CFI_FLASH_STATUS_POLL By defining CONFIG_SYS_CFI_FLASH_STATUS_POLL, DQ7 is polled to detect the chip busy status. This is now used instead of the data toggle method which is used historically by default in the common CFI driver. With this change a problem with not written data is solved on this board, where a 32 byte block of data is still erased instead of filled with the correct content after these commands: => erase 0xfc100000 +0x1000000 .................................................................... done Erased 128 sectors => cp.b 0x100000 0xfc100000 0x1000000 Copy to Flash... done => cmp.b 0x100000 0xfc100000 0x1000000 byte at 0x00d0d6c0 (0x00) != byte at 0xfcd0d6c0 (0xff) Total of 12637888 bytes were the same Signed-off-by: Stefan Roese <sr@denx.de>
