2012-07-21ARM1136: Fix cache range checksBenoît Thébaudeau
bad_cache_range actually returned true if the range was OK, but it was used according to its name, which resulted in all valid dcache range invalidate/flush operations being dropped. Hence, most DMA transfers resulted in garbage data. This patch renames this function according to what it does, and it fixes the interpretation of its return value by other functions. The chosen naming is the same as for ARM926EJ-S in order to be consistent.

2012-04-16ARM1136: add cache flush and invalidate operationsAnatolij Gustschin
Since commit 5c1ad3e6f8ae578bbe30e09652f1531e9bc22031 (net: fec_mxc: allow use with cache enabled) the FEC_MXC driver uses flush_dcache_range() and invalidate_dcache_range() functions. This driver is also configured for ARM1136 based 'flea3' and 'mx35pdk' boards which currently do not build as there are no ARM1136 specific flush_dcache_range() and invalidate_dcache_range() functions. Add various ARM1136 cache functions to fix building for 'flea3' and 'mx35pdk'.

2012-03-30arm: Use common .lds file where possibleSimon Glass

2012-02-12mmc: access mxcmmc from mx31 boardsHelmut Raiger
This patch modifies mxcmmc.c to be used not only by i.MX27 but also by i.MX31 boards. Both use the same SD controller, but have different clock set-ups. The i.MX27 imx_get_XXXclock functions are made static to generic.c and a public mxc_get_clock() function is provided. Pins, base address and prototypes for an i.MX31 specific board_init_mmc() are provided. Some of the i.MX27 clock getters are unused and marked as such to avoid warnings (./MAKEALL -s mx27), but the code was left in for future use.

2011-11-03Reduce build timesWolfgang Denk
U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.
