[U-Boot] [PATCH] powerpc/mpc85xx: Enabling CPC conditionally based on hwconfig options
by Sandeep Singh 02 Jul '13

[U-Boot] [PATCH 0/3 v2] video: lcd: splash screen prepare changes
by Robert Winkler 01 Jul '13

01 Jul '13

The first 2 patches are the result of discussion in these threads: http://lists.denx.de/pipermail/u-boot/2013-May/155463.html http://lists.denx.de/pipermail/u-boot/2013-June/155630.html http://lists.denx.de/pipermail/u-boot/2013-June/155632.html The upshot is, move splash_screen_prepare to a common location so it can be used in cfb_console.c and (possibly) make it weak. The first patch can be accepted without the last two. The third patch is a fix for cm_t35 that's only necessary if we make it weak.

[U-Boot] [PATCH] lcd: remove unaligned access in lcd_dt_simplefb_configure_node()
by Stephen Warren 01 Jul '13

01 Jul '13

From: Stephen Warren <swarren(a)nvidia.com> Some ARM compilers may emit code that makes unaligned accesses when faced with constructs such as: const char format[] = "r5g6b5"; Make this data static since it doesn't chagne; the compiler will simply place it into the .rodata section directly, and avoid any unaligned run- time initialization.
