2012-06-28	51885a7 Browse files » Change byte order detection mechanism to kernel style ... The Linux Kernel defines only one of __LITTLE_ENDIAN and __BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then be tested with #if __BYTE_ORDER == __xx_ENDIAN. As we tend to use a lot of Kernel code in barebox we switch to use the kernel way of determing the byte order. As this always causes a lot of confusion add a check to include/common.h to make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined.

2012-04-05	7eebd3b Browse files » cfi flash: Fix alignment problem ... The intel cfi buffer write has a problem with writing when the alignment of the buffer in memory is smaller than the flash bus width. This patch fixes a alignment problem which may show during this scenario: - 32 or 64 attached NOR flash - flashing an image directly from network to the nor flash The involved network driver is "smc9111.c". The data that comes from the network stack and should be written into the flash isn't 32 bit aligned (at least with this network driver). This is probably due to the 48 bit wide ethernet addresses. However the "cfi_flash.c" driver doesn't handle this situation, and accesses the not-aligned address with a 32 bit pointer. This patch fixes the problem by reducing the access width if an aligment problem between source and destination is found.
