* Use jr as register jump instructionShinya Kuribayashi2008-04-18-6/+6
| | | | | | | | | | Current assembler codes are inconsistent in the way of register jump instruction usage; some use jr, some use j. Of course GNU as allows both usages, but as can be expected from `Jump Register' the mnemonic `jr' is more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage at all.

* [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] 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/+7
| | | | | | | | | | 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.

* [MIPS] Fix $gp usageShinya Kuribayashi2007-10-21-6/+13
| | | | | | | | | | | | | | | | | | | | Now we load $gp with _GLOBAL_OFFSET_TABLE_, but this is incorrect use. As a general principle, we should use _gp for $gp. Thanks to linker script's help we fortunately have _gp which equals to _GLOBAL_OFFSET_TABLE_. But once _gp gets out of alignment, we will not be able to access to GOT entires, global variables and procedure entry points. The right thing to do is to use _gp. This patch also introduce a new symbol `.gpword _GLOBAL_OFFSET_TABLE_' which holds the offset from _gp. When updating GOT entries, we use this offset and _gp to calculate the final _GLOBAL_OFFSET_TABLE_. This patch is originally submitted by Vlad Lungu <vlad@comsys.ro>, then I made some change to leave over num_got_entries.

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-9/+13
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
