| * MPC5200: workaround data corruption for unaligned local bus accessesWolfgang Denk2010-06-23-0/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC5200 has a nasty problem that will cause silent data corruption when performing unaligned 16 or 32 byte accesses when reading from the local bus - typically this affects reading from flash. The problem can be easily shown: => md fc0c0000 10 fc0c0000: 323e4337 01626f6f 74636d64 3d72756e 2>C7.bootcmd=run fc0c0010: 206e6574 5f6e6673 00626f6f 7464656c net_nfs.bootdel fc0c0020: 61793d35 00626175 64726174 653d3131 ay=5.baudrate=11 fc0c0030: 35323030 00707265 626f6f74 3d656368 5200.preboot=ech => md fc0c0001 10 fc0c0001: 65636801 00000074 0000003d 00000020 ech....t...=... fc0c0011: 0000005f 00000000 00000074 00000061 ..._.......t...a fc0c0021: 00000000 00000064 00000065 00000035 .......d...e...5 fc0c0031: 00000000 00000062 0000003d 0000006f .......b...=...o => md.w fc0c0001 10 fc0c0001: 0000 3701 0000 6f74 0000 643d 0000 6e20 ..7...ot..d=..n fc0c0011: 0000 745f 0000 7300 0000 6f74 0000 6c61 ..t_..s...ot..la This commit implements a workaround at least for the most blatant problem: using memcpy() from NOR flash. We rename the assembler routine into __memcpy() and provide a wrapper, which will use a byte-wise copy loop for unaligned source or target addresses when reading from NOR flash, and branch to the optimized __memcpy() in all other cases, thus minimizing the performance impact.

| * PXA: Align stack to 8 bytesMarek Vasut2010-06-13-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Part of this patch is by: Mikhail Kshevetskiy. 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.

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. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

| * | | DaVinci: Improve DaVinci SPI speed.Delio Brignoli2010-06-08-34/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
