Do you setup host bridge window base & size? Exactly, I didn’t set it before. Suppose, PCI devices on bus 0 should work, right ? Regards, Gavin

[U-Boot] [PATCH] cfi_flash: Add optional config register write to cfi-detection
by Stefan Roese 17 Dec '10

17 Dec '10

This patch adds the possibility to (optinally) write to the flash configuration register. The Intel style CFI chips support such a register that can be used to configure the operation mode to a non-default value. This method will be used by the t3corp board, which needs to configure the DS617 Xilinx flash for async read mode.

[U-Boot] [PATCH] cfi_flash: Use flash_read32() in sector_erased()
by Stefan Roese 17 Dec '10

17 Dec '10

The function sector_erased() is modified to not use pointer access, but to use the correct accessor functions. This fixes a problem on the t3corp board with the Xilinx DS617 flash chips. Here a board specific accessor function is needed to read from flash in 32bit mode. This patch enables such an operation mode.

[U-Boot] [PATCH] cfi_flash: Fix problems with status/id read mode

[U-Boot] [PATCH] ppc4xx/POST: Change ethernet test loop count to a default of 10
by Stefan Roese 17 Dec '10

17 Dec '10

This patch changes the PPC4xx ethernet POST loop test count from currently 192 (256 - 64) to a default of 10. While doing this the max frame size is increased. Each loop run uses a different frame size, starting with a max of 1514 bytes, down to 64. The default loop count of 10 can be overriden using CONFIG_SYS_POST_ETH_LOOPS in the board config header. The TEST_NUM loop has been removed as it was never used. The main reason for this change is to reduce the boot time on boards using this POST test, like the lwmon5 board. This change reduces the boot time by about 600ms on the lwmon5 board. Signed-off-by: Stefan Roese <sr(a)denx.de> Cc: Wolfgang Denk <wd(a)denx.de> --- Wolfgang, I changed the loop to start with the max frame size (so that this value is really used) and decrease the size to the min value. Testing on lwmon5 showed that 1514 is the biggest value for this test to pass. Let me know if you ack this patch version and I'll queue it for next in my ppc4xx repository.

[U-Boot] [PATCH] ppc4xx: Update lwmon5 board support
by Stefan Roese 17 Dec '10

17 Dec '10

This patch includes the following changes for the lwmon5 board support: - Enable cache in SDRAM - Use common EHCI driver instead of the PPC4xx specific OHCI driver This can be done since only high-speed devices are connected. - Remove cached TLB entry again after ECC setup - Use correct define for cache enabling (CONFIG_4xx_DCACHE instead of CONFIG_SYS_ENABLE_SDRAM_CACHE) - Enable FIT image support Signed-off-by: Stefan Roese <sr(a)denx.de> --- board/lwmon5/sdram.c | 22 ++++++++++++++++++---- include/configs/lwmon5.h | 22 ++++++++++++++-------- 2 files changed, 32 insertions(+), 12 deletions(-) diff --git a/board/lwmon5/sdram.c b/board/lwmon5/sdram.c index f90efeb..b64b35a 100644 --- a/board/lwmon5/sdram.c +++ b/board/lwmon5/sdram.c @@ -45,10 +45,10 @@ * memory. * * If at some time this restriction doesn't apply anymore, just define - * CONFIG_SYS_ENABLE_SDRAM_CACHE in the board config file and this code should setup + * CONFIG_4xx_DCACHE in the board config file and this code should setup * everything correctly. */ -#ifdef CONFIG_SYS_ENABLE_SDRAM_CACHE +#ifdef CONFIG_4xx_DCACHE #define MY_TLB_WORD2_I_ENABLE 0 /* enable caching on SDRAM */ #else #define MY_TLB_WORD2_I_ENABLE TLB_WORD2_I_ENABLE /* disable caching on SDRAM */ @@ -220,18 +220,32 @@ phys_size_t initdram (int board_type) program_tlb(0, CONFIG_SYS_SDRAM_BASE, CONFIG_SYS_MBYTES_SDRAM << 20, MY_TLB_WORD2_I_ENABLE); +#if defined(CONFIG_DDR_ECC) +#if defined(CONFIG_4xx_DCACHE) + /* + * If ECC is enabled, initialize the parity bits. + */ + program_ecc(0, CONFIG_SYS_MBYTES_SDRAM << 20, 0); +#else /* CONFIG_4xx_DCACHE */ /* * Setup 2nd TLB with same physical address but different virtual address * with cache enabled.
