MPC512x: workaround data corruption for unaligned local bus accesses

2010-06-29T12:41:37Z

Commit 460c2ce3 "MPC5200: workaround data corruption for unaligned local bus accesses" fixed the problem for MPC5200 only, but MPC512x is affected as well, so apply the same fix here, too. Signed-off-by: Wolfgang Denk Cc: Detlev Zundel Cc: Anatolij Gustschin Acked-by: Detlev Zundel

MPC5200: workaround data corruption for unaligned local bus accesses

2010-06-23T00:09:20Z

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. Tested on lite5200b and TQM5200S. Signed-off-by: Wolfgang Denk Cc: Detlev Zundel

mpc83xx: don't shift pre-shifted ACR, SPCR, SCCR bitfield masks in cpu_init.c

2010-05-21T20:22:39Z

commit c7190f028fa950d4d36b6d0b4bb3fc72602ec54c "mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields" incorrectly shifted _ (e.g. ACR_PIPE_DEP) values that were preshifted by their definition in mpc83xx.h. this patch removes the unnecessary shifting for the newly utilized mask values in cpu_init.c, and prevents seemingly unrelated symptoms such as an mpc8379erdb board from locking up whilst performing a networking operation, e.g. a tftp.

mpc83xx: fix NAND bootstrap too big error

2010-05-17T19:44:25Z

commit 167cdad1372917bc11c636c359aad02625291fa9 "SERIAL: Enable port-mapped access" inadvertently broke 83xx nand boards by converting NS16550_init to use io accessors, which expanded the size of the generated code. this patch fixes the problem by removing icache functions from the nand builds, which somewhat follows commit 1a2e203b31d33fb720f2cf1033b241ad36ab405a "mpc83xx: turn on icache in core initialization to improve u-boot boot time" Signed-off-by: Kim Phillips
