[U-Boot] [PATCH] part: Drop duplication declaration of block_dev_desc_t
by Simon Glass 25 Jan '16

25 Jan '16

This is already defined in ide.h, which part.h includes. So we don't need the duplicate typedef. At least with my old blackfin gcc 4.3.5 tool chain, this causes an error.

[U-Boot] [PATCH] bootm: fix size arg of flush_cache() in bootm_load_os().
by Purna Chandra Mandal 25 Jan '16

25 Jan '16

Variable _load_end_ points to end address of uncompressed buffer (*not* uncomress_buffer_end / sizeof(ulong)), so multipling uncompressed size with sizeof(ulong) is grossly incorrect in flush_cache(). It might lead to access of address beyond valid memory range and hang the CPU. Tested on MIPS architecture by using compressed(gzip, lzma) and uncompressed uImage.

[U-Boot] [PATCH 1/2] kbuild: Add clang detection

We also cannot detect clang after including the arch Makefile, because powerpc wants to know about clang. Solve this by using an deferred variable.

[U-Boot] [PATCH 0/2] Move commands into their own directory
by Simon Glass 25 Jan '16

25 Jan '16

This series makes a start at cleaning up the common directory. At present it includes any code that is not board-specific, a library or a driver. This means there are a lot of files, including all the commands. Moving the command files into their own directory makes them easier to find and is more logical than having them all in common/.

[U-Boot] [PATCH 1/2] checkpatch: ignore request to use ether_addr_copy()
by Stephen Warren 25 Jan '16

25 Jan '16

From: Stephen Warren <swarren(a)nvidia.com> The Linux kernel, from which checkpatch originates, contains function ether_addr_copy() to copy Ethernet MAC addresses, and checkpatch warns that it should be used in preference to memcpy() where appropriate. U-Boot doesn't contain ether_addr_copy(), so tell checkpatch not to issue this warning.

[U-Boot] [PATCH] arm: cache: Implement cache range check for v7
by Marek Vasut 25 Jan '16

25 Jan '16

Add code to aid tracking down cache alignment issues. In case DEBUG is defined in the cache.c, this code will check alignment of each attempt to flush/invalidate data cache and print a warning if the alignment is incorrect. If DEBUG is not defined, this code is optimized out.
