2011-07-17Remove volatile qualifier in get_ram_size() callsAlbert ARIBAUD
Checkpatch.pl complains about the volatile qualifier in calls to get_ram_size(). Remove this qualifier in the prototype and in the calls where it is useless, and leave it only in the function body where it is needed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
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>
2011-07-17arm: add CONFIG_MACH_TYPE setting and documentationIgor Grinberg
CONFIG_MACH_TYPE is used to set the machine type number in the common arm code instead of setting it in the board code. Boards with dynamically discoverable machine types can still set the machine type number in the board code. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>

2011-07-04arm/kirkwood: if CONFIG_SOFT_I2C is set don't set CONFIG_I2C_MVTWSIHolger Brunck
Some boards e.g. keymile arm boards have CONFIG_CMD_I2C switched on but they use soft i2c on kirkwood. So don't switch CONFIG_I2C_MVTWSI on in this case.

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: add PL310 support to u-bootAneesh V
PL310 is the L2$ controller from ARM used in many SoCs including the Cortex-A9 based OMAP4430 Add support for some of the key PL310 operations - Invalidate all - Invalidate range - Flush(clean & invalidate) all - Flush range Signed-off-by: Aneesh V <aneesh@ti.com>
2011-07-04arm: minor fixes for cache and mmu handlingAneesh V
1. make sure that page table setup is not done multiple times 2. flush_dcache_all() is more appropriate while disabling cache than a range flush on the entire memory(flush_cache()) Provide a default implementation for flush_dcache_all() for backward compatibility and to avoid build issues. Signed-off-by: Aneesh V <aneesh@ti.com>
2011-07-04armv7: integrate cache maintenance supportAneesh V
- Enable I-cache on bootup - Enable MMU and D-cache immediately after relocation - Do necessary initialization before enabling d-cache and MMU - Changes to cleanup_before_linux() - Make changes according to the new framework Signed-off-by: Aneesh V <aneesh@ti.com>
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>
