In the commit 79b51ff8205f0354d5300570614c1d2db499679c ([MIPS] cpu/mips/ Makefile: Split [CS]OBJS onto separate lines), I wrongly deleted a START line. This patch puts it back. Signed-off-by: Shinya Kuribayashi <shinya.kuribayashi@necel.com>
2009-01-28usb.h: use standard __LITTLE_ENDIAN from Linux headersMike Frysinger
Rather than forcing people to define a custom "LITTLEENDIAN", just use the __LITTLE_ENDIAN one from the Linux byteorder headers that every arch is already setting up. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Remy Bohmer <linux@bohmer.net>
2009-01-27MIPS: Add flush_dcache_range() and invalidate_dcache_range()Stefan Roese
This patch adds flush_/invalidate_dcache_range() to the MIPS architecture. Those functions are needed for the upcoming dcache support for the USB EHCI driver. I chose this API because those cache handling functions are already present in the PPC architecture.

2008-12-10MIPS: Add CONFIG_SKIP_LOWLEVEL_INITStefan Roese
This patch adds the CONFIG_SKIP_LOWLEVEL_INIT option to start.S. This enables support for boards where the lowlevel initialization is already done when U-Boot runs (e.g. via OnChip ROM).

At a lot of places in the code the PIPE_INTERRUPT flags and friends are used wrong. The wrong bits are compared to this flag resulting in wrong conditions. Also there are macros that should be used for PIPE_* flags. This patch tries to fix them all, however, I was not able to test the changes, because I do not have any of these boards. Review required!

2008-05-06[MIPS] cpu/mips/cache.S: Fix build warningShinya Kuribayashi
Some old GNU assemblers, such as v2.14 (ELDK 3.1.1), v2.16 (ELDK 4.1.0), warns illegal global symbol references by bal (and jal also) instruction. This does not happen with the latest binutils v2.18. Here's an example on gth2_config: mips_4KC-gcc -D__ASSEMBLY__ -g -Os -D__KERNEL__ -DTEXT_BASE=0x90000000 -I/home/skuribay/devel/u-boot.git/include -fno-builtin -ffreestanding -nostdinc -isy stem /opt/eldk311/usr/bin/../lib/gcc-lib/mips-linux/3.3.3/include -pipe -DCONFIG_MIPS -D__MIPS__ -G 0 -mabicalls -fpic -pipe -msoft-float -march=4kc -mtune=4k c -EB -c -o cache.o cache.S cache.S: Assembler messages: cache.S:243: Warning: Pretending global symbol used as branch target is local. cache.S:250: Warning: Pretending global symbol used as branch target is local. In principle, gas might be sensitive to global symbol references in PIC code because they should be processed through GOT (global offset table). But if `bal' instruction is used, it results in PC-based offset jump. This is the cause of this warning. In practice, we know it doesn't matter whether PC-based reference or GOT- based. As for this case, both will work before/after relocation. But let's fix the code. This patch explicitly sets up a target address, then jump there. Here's an example of disassembled code with/without this patch. 90000668: 1485ffef bne a0,a1,90000628 <mips_cache_reset+0x20> 9000066c: ac80fffc sw zero,-4(a0) 90000670: 01402821 move a1,t2 -90000674: 0411ffba bal 90000560 <mips_init_icache> -90000678: 01803021 move a2,t4 -9000067c: 01602821 move a1,t3 -90000680: 0411ffcc bal 900005b4 <mips_init_dcache> -90000684: 01a03021 move a2,t5 -90000688: 03000008 jr t8 -9000068c: 00000000 nop +90000674: 01803021 move a2,t4 +90000678: 8f8f83ec lw t7,-31764(gp) +9000067c: 01e0f809 jalr t7 +90000680: 00000000 nop +90000684: 01602821 move a1,t3 +90000688: 01a03021 move a2,t5 +9000068c: 8f8f81e0 lw t7,-32288(gp) +90000690: 01e0f809 jalr t7 +90000694: 00000000 nop +90000698: 03000008 jr t8 +9000069c: 00000000 nop Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>

2008-05-03[MIPS] cpu/mips/config.mk: Fix GNU assembler minor version pickerShinya Kuribayashi
Current trick to pick up GNU assembler minor version uses a dot(.) as a delimiter, and take the second field to obtain minor version number. But as can be expected, this doesn't work with a version string which has dots more than needs. Here's an example: $ mips-linux-gnu-as --version | grep 'GNU assembler' GNU assembler (Sourcery G++ Lite 4.2-129) 2.18.50.20080215 $ mips-linux-gnu-as --version | grep 'GNU assembler' | cut -d. -f2 2-129) 2 $ This patch restricts the version format to 2.XX.XX... This will work in most cases. $ mips-linux-gnu-as --version | grep 'GNU assembler' | egrep -o '2\.[0-9\.]+' 2.18.50.20080215 $ mips-linux-gnu-as --version | grep 'GNU assembler' | egrep -o '2\.[0-9\.]+' | cut -d. -f2 18 $ Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>

2008-04-18Use jr as register jump instructionShinya Kuribayashi
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.

2008-03-25[MIPS] Fix I-/D-cache initialization loopsShinya Kuribayashi
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.

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.

2008-03-25[MIPS] Request for the 'mips_cache_lock()' removalShinya Kuribayashi
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.

2007-10-21[MIPS] Fix $gp usageShinya Kuribayashi
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.

2006-09-01Add support for a saving build objects in a separate directory.Marian Balakowicz
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.
