From 409a07c9d72b0d833c1cce264bdb4bb2628fe28e Mon Sep 17 00:00:00 2001 From: "George G. Davis" Date: Tue, 11 May 2010 10:15:36 -0400 Subject: [PATCH 01/31] ARM1136: Fix cache_flush() error and correct cpu_init_crit() comments The ARM1136 cache_flush() function uses the "mcr p15, 0, rn, c7, c7, 0" instruction which means "Invalidate Both Caches" when in fact the intent is to clean and invalidate all caches. So add an "mcr p15, 0, %0, c7, c10, 0" instruction to "Clean Entire Data Cache" prior to the "Invalidate Both Caches" instruction to insure that memory is consistent with any dirty cache lines. Also fix a couple of "flush v*" comments in ARM1136 cpu_init_crit() so that they correctly describe the actual ARM1136 CP15 C7 Cache Operations used. Signed-off-by: George G.

The following changes were necessary prerequisites for the addition of other SoCs based on ARM1176. Existing board's (SMDK6400) configuration has been modified to keep behavior unchanged despite these changes. 1. Peripheral port remap configurability The earlier code had hardcoded remap values specific to s3c64xx in start.S. This change makes the peripheral port remap addresses and sizes configurable. 2. U-Boot code relocation support Most architectures allow u-boot code to run initially at a different address (possibly in NOR) and then get relocated to its final resting place in RAM. Added support for this capability in ARM1176 architecture. 3. Disable TCM if necessary If a ROM based bootloader happened to have initialized TCM, we disable it here to keep things sane. 4. Remove unnecessary SoC specific includes ARM1176 code does not really need this SoC specific include. The presence of this include prevents builds on other ARM1176 archs. 5. Modified virt-to-phys conversion during MMU disable The original MMU disable code masks out too many bits from the load address when it tries to figure out the physical address of the jump target label. Consequently, it ends up branching to the wrong address after disabling the MMU.

I have updated this patch based on the comments [1] by Wolfgang Denk and removed unused variables. [1][http://lists.denx.de/pipermail/u-boot/2010-May/071728.html] Reduce the number of reads per byte transferred on the BUF register from 2 to 1 and take advantage of the TX buffer in the SPI module. On LogicPD OMAP-L138 EVM, SPI read throughput goes up from ~0.8Mbyte/s to ~1.3Mbyte/s. Tested with a 2Mbyte image file. Remove unused variables in the spi_xfer() function.

The following changes were necessary prerequisites for the addition of other SoCs based on ARM1176. Existing board's (SMDK6400) configuration has been modified to keep behavior unchanged despite these changes. 1. Peripheral port remap configurability The earlier code had hardcoded remap values specific to s3c64xx in start.S. This change makes the peripheral port remap addresses and sizes configurable. 2. U-Boot code relocation support Most architectures allow u-boot code to run initially at a different address (possibly in NOR) and then get relocated to its final resting place in RAM. Added support for this capability in ARM1176 architecture. 3. Disable TCM if necessary If a ROM based bootloader happened to have initialized TCM, we disable it here to keep things sane. 4. Remove unnecessary SoC specific includes ARM1176 code does not really need this SoC specific include. The presence of this include prevents builds on other ARM1176 archs. 5. Modified virt-to-phys conversion during MMU disable The original MMU disable code masks out too many bits from the load address when it tries to figure out the physical address of the jump target label. Consequently, it ends up branching to the wrong address after disabling the MMU.

I have updated this patch based on the comments [1] by Wolfgang Denk and removed unused variables. [1][http://lists.denx.de/pipermail/u-boot/2010-May/071728.html] Reduce the number of reads per byte transferred on the BUF register from 2 to 1 and take advantage of the TX buffer in the SPI module. On LogicPD OMAP-L138 EVM, SPI read throughput goes up from ~0.8Mbyte/s to ~1.3Mbyte/s. Tested with a 2Mbyte image file. Remove unused variables in the spi_xfer() function.

Stack must be aligned to 8 bytes on PXA (possibly all armv5te) for LDRD/STRD instructions. In case LDRD/STRD is issued on an unaligned address, the behaviour is undefined. The issue was observed when working with the NAND code, which was rendered disfunctional. Also, the vsprintf() function had serious problems with printing 64bit wide long longs. After aligning the stack, this wrong behaviour is no longer present. Tested on: Marvell Littleton PXA310 board Toradex Colibri PXA320 board Aeronix Zipit Z2 PXA270 handheld Voipac PXA270 board Signed-off-by: Marek Vasut --- arch/arm/cpu/pxa/start.S | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/arch/arm/cpu/pxa/start.S b/arch/arm/cpu/pxa/start.S index 63ab0c591..3989fa61b 100644 --- a/arch/arm/cpu/pxa/start.S +++ b/arch/arm/cpu/pxa/start.S @@ -140,7 +140,10 @@ stack_setup: #ifdef CONFIG_USE_IRQ sub r0, r0, #(CONFIG_STACKSIZE_IRQ+CONFIG_STACKSIZE_FIQ) #endif /* CONFIG_USE_IRQ */ - sub sp, r0, #12 /* leave 3 words for abort-stack */ + sub r0, r0, #12 /* leave 3 words for abort-stack */ + bic sp, r0, #7 /* NOTE: stack MUST be aligned to */ + /* 8 bytes in case we want to use */ + /* 64bit datatypes (eg.
