2011-07-18ARM: MX5: Fix broken leftover TO-2 errata workaroundDavid Jander
This check was broken. r3 does not contain the silicon revision anymore, so we need to reload it. Also, this errata only applies to i.MX51. Signed-off-by: David Jander <david@protonic.nl> Acked-by: Stefano Babic <sbabic@denx.de>
2011-07-17ARM: add missing CONFIG_SKIP_LOWLEVEL_INIT for armv7Rob Herring
cpu_init_crit can be skipped, but the code is still enabled requiring a platform to supply lowlevel_init. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Cc: Albert ARIBAUD <albert.aribaud@free.fr>

2011-07-04OMAP[34]: fix broken timerJohn Rigby
As implemented now the timer used to implement __udelay counts to 0xffffffff and then gets stuck there because the the programmed reload value is 0xffffffff. This value is not only wrong but illegal according to the reference manual. One can reproduce the bug by leaving a board at the u-boot prompt for sometime then issuing a sleep command. The sleep will hang forever. The timer is a count up timer that reloads as it rolls over from 0xffffffff so the correct load value is 0. Change TIMER_LOAD_VAL from 0xffffffff to 0 and introduce a new constant called TIMER_OVERFLOW_VAL set to 0xffffffff.

2011-07-04armv7: rename cache related CONFIG flagsAneesh V
Replace the cache related CONFIG flags with more meaningful names. Following are the changes: CONFIG_L2_OFF -> CONFIG_SYS_L2CACHE_OFF CONFIG_SYS_NO_ICACHE -> CONFIG_SYS_ICACHE_OFF CONFIG_SYS_NO_DCACHE -> CONFIG_SYS_DCACHE_OFF Signed-off-by: Aneesh V <aneesh@ti.com> V2: * Changed CONFIG_L2_OFF -> CONFIG_SYS_NO_L2CACHE V4: * Changed all three flags to the final names suggested as above and accordingly changed the commit message
2011-07-04armv7: cache maintenance operations for armv7Aneesh V
- Add a framework for layered cache maintenance - separate out SOC specific outer cache maintenance from maintenance of caches known to CPU - Add generic ARMv7 cache maintenance operations that affect all caches known to ARMv7 CPUs. For instance in Cortex-A8 these opertions will affect both L1 and L2 caches. In Cortex-A9 these will affect only L1 cache - D-cache operations supported: - Invalidate entire D-cache - Invalidate D-cache range - Flush(clean & invalidate) entire D-cache - Flush D-cache range - I-cache operations supported: - Invalidate entire I-cache - Add maintenance functions for TLB, branch predictor array etc. - Enable -march=armv7-a so that armv7 assembly instructions can be used Signed-off-by: Aneesh V <aneesh@ti.com>

2011-03-27arm: fix incorrect monitor protection region in FLASHPo-Yu Chuang
Monitor protection region in FLASH did not cover .rel.dyn and .dynsym sections, because it uses __bss_start to compute monitor_flash_len. Use _end instead. Add _end to linker scripts for end of u-boot image Add _end_ofs to all the start.S. Signed-off-by: Po-Yu Chuang <ratbert@faraday-tech.com>
2011-03-27rename _end to __bss_end__Po-Yu Chuang

2010-12-09armv7: fix relocation skipAndreas Bießmann
I doubt the stack_setup() was defective before: we load the current location of _start and compare against destination of relocate_code(). If we are already there we shoud skip the relocation and jump over to clear_bss. Before the clear_bss was also skipped. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
2010-12-09arm: fixloop(): do not use r8 for relocationAndreas Bießmann
r8 is used for global_data and should therefore be left alone! For C code the compiler flag --fixed-r8 does the job, but in assembler we need to be aware of that fact. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
2010-12-09arm: relocate_code(): do not set register uselessAndreas Bießmann
In case we are still at relocation target address before relocation we do not need to load the registers needed for relocation. We should instead skip the whole relocation part and jump over to clear_bss immediately. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
2010-12-09arm: copy_loop(): use scratch registerAndreas Bießmann
This patch uses r1 as scratch register for copy_loop(). Therefore we do not longer need r7 for the storage of relocate_code()'s 'addr_moni' (the destination address of relocation). Therefore r7 can be used later on for other purposes. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
