arm: armv7: omap3: Fix restore sequence in lowlevel_init

2012-10-08T18:15:04+00:00

The restore sequence in lowlevel_init was in the wrong order,
causing lr to lose its original value and be set equal to ip
instead. Also, its use of the stack clashes with that of
s_init, so move the s_init call after the restore and turn
it  into a tail-optimized branch.

arm: rmobile: bugfix: wrong register saving in lowlevel_init

2012-10-08T18:15:04+00:00

lowlevel_init() of rmobile badly assumed that ip register holds return address.
The commit "63ee53a7 armv7 cpu_init_crit: Simplify code" breaks this assumption.
This patch removes this bad assumption and simplify code.

arm: armv7: temporarily set -mno-unaligned-access

2012-10-05T19:24:22+00:00

This patch aims at ensuring that the 2012.10 release works
out-of-the-box on as many targets as possible, by reinstating
commit 5347560f5427bcdd48a563b62180481606ac8044, which adds
option -mno-unaligned-access to armv7 builds.

This patch will be overriden immediately after release of 2012.10.

armv7 cpu_init_crit: Simplify code

2012-10-04T12:19:07+00:00

We don't need to return to cpu_init_crit after calling lowlevel_init, so
lowlevel_init can directly return to the caller of cpu_init_crit.

kirkwood: implement kw_sdram_size_adjust

2012-10-03T11:13:13+00:00

Size of the SDRAM chips might differ between any two (otherwise
identical) instances of the same board.

So add a function kw_sdram_size_adjust() which reads out the current
ram size for a given bank, and adjusts the Kirkwood's SDRAM window size
register accordingly.

kirkwood: implement kw_sdram_bs_set()

2012-10-03T11:13:13+00:00

Some boards might be equipped with different SDRAM configurations.
When that is the case, CPU CS Window Size Register (CS[0]n Size)
should be set to the biggest value through board.cfg file; then its
value can be fixed at runtime according to the detected SDRAM size.

Therefore, implement kw_sdram_bs_set().
