* [MIPS] Introduce _machine_restartShinya Kuribayashi2008-03-25-8/+42
| | | | | | Handles machine specific functions by using weak functions. Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>
* [MIPS] Cleanup CP0 Status initializationShinya Kuribayashi2008-03-25-9/+25
| | | | | | | | Add setup_c0_status from Linux. For the moment we disable interrupts, set CU0, mark the kernel mode, and clear ERL and EXL. This is good enough for reset-time configuration and will work well across most processors. Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>
* [MIPS] Initialize CP0 Cause before setting up CP0 Status registerShinya Kuribayashi2008-03-25-3/+3
| | | | | | | Without this change, we'll be suffering from deffered WATCH exception once Status.EXL is cleared. Make sure Cause.WP is cleared. Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>

* [MIPS] Implement flush_cache()Shinya Kuribayashi2008-03-25-0/+22
| | | | | | | | | We do Hit_Writeback_Inv_D and Hit_Invalidate_I. You might think that you don't need to do Hit_Invalidate_I, but flush_cache() needs it since this function is used not only in U-Boot specfic programs but also at loading target binaries.

* [MIPS] Fix I-/D-cache initialization loopsShinya Kuribayashi2008-03-25-39/+76
| | | | | | | | | | | | | Currently we do 1) Index_Store_Tag_I, 2) Fill and 3) Index_Store_Tag_I again per a loop for I-cache initialization. But according to 'See MIPS Run', we're encouraged to use three separate loops rather than combining them *for both I- and D-cache*. This patch tries to fix this. In accordance with fixing above, mips_init_[id]cache are separated from mips_cache_reset(), and rewrite cache loops are completely rewritten with useful macros.

* [MIPS] Replace memory clearance code with f_fill64Shinya Kuribayashi2008-03-25-15/+28

* [MIPS] cpu/mips/cache.S: Introduce NESTED/LEAF/END macrosShinya Kuribayashi2008-03-25-18/+416
| | | | | | | | | | This patch replaces the current function definitions with NESTED, LEAF and END macro. They specify some more additional information about the function; an alignment of symbol, type of symbol, stack frame usage, etc. These information explicitly tells the assembler and the debugger about the types of code we want to generate.

* [MIPS] Request for the 'mips_cache_lock()' removalShinya Kuribayashi2008-03-25-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial intension of having mips_cache_lock() was to use the cache as memory for temporary stack use so that a C environment can be set up as early as possible. But now mips_cache_lock() follow lowlevel_init(). We've already have the real memory initilaized at this point, therefore we could/should use it. No reason to lock at all. Other problems: Cache locking is not consistent across MIPS implementaions. Some imple- mentations don't support locking at all. The style of locking varies - some support per line locking, others per way, etc. Some parts use bits in status registers instead of cache ops. Current mips_cache_lock() is not necessarily general-purpose. And this is worthy of special mention; once U-Boot/MIPS locks the lines, they are never get unlocked, so the code relies on whatever gets loaded after U-Boot to re-initialize the cache and clear the locks. We're sup- posed to have CFG_INIT_RAM_LOCK and unlock_ram_in_cache() implemented, but leave the situation as it is for a long time. For these reasons, I proposed the removal of mips_cache_lock() from the global start-up code. This patch adds CFG_INIT_RAM_LOCK_MIPS to make existing users aware that *things have changed*. If he wants the same behavior as before, he needs to have CFG_INIT_RAM_LOCK_MIPS in his config file. If we don't have any regression report through several releases, then we'll remove codes entirely.

* lwmon5 SYSMON POST: fix backlight controlYuri Tikhonov2008-03-25-1/+4
| | | | | | | | | | | | If the LWMON5 config has SYSMON POST among CONFIG_POSTs which may be run on the board, then the SYSMON POST controls the display backlight (doesn't switch backlight ON if POST FAILED, and does switch the backlight ON if PASSED). If not, then the video driver controls the display backlight (just switch ON the backlight upon initialization). Signed-off-by: Yuri Tikhonov <yur@emcraft.com>

| | * | | libfdt: Remove no longer used code from fdt_node_offset_by_compatible()David Gibson2008-03-18-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since fdt_node_offset_by_compatible() was converted to the new fdt_next_node() iterator, a chunk of initialization code became redundant, but was not removed by oversight. This patch cleans it up. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
| | * | | libfdt: Trivial cleanup for CHECK_HEADER)David Gibson2008-03-18-17/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the CHECK_HEADER() macro is defined local to fdt_ro.c. However, there are a handful of functions (fdt_move, rw_check_header, fdt_open_into) from other files which could also use it (currently they open-code something more-or-less identical). Therefore, this patch moves CHECK_HEADER() to libfdt_internal.h and uses it in those places. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

| | * | | libfdt: Fix NOP handling bug in fdt_add_subnode_namelen()David Gibson2008-03-18-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fdt_add_subnode_namelen() has a bug if asked to add a subnode to a node which has NOP tags interspersed with its properties. In this case fdt_add_subnode_namelen() will put the new subnode before the first NOP tag, even if there are properties after it, which will result in an invalid blob.
