* mips32: detect L1 cache sizes if they're not definedPaul Burton2013-11-09-13/+77
| | | | | | | | | | | | | | | | For boards such as the MIPS Malta with an FPGA core card it is desirable to be able to detect the L1 cache sizes at runtime, since they are not dependant upon the board but on the FPGA bitstream in use. This patch performs that detection when the CONFIG_SYS_[DI]CACHE_SIZE macros are not defined by the board configuration. In cases where the sizes are detected this patch also removes the restriction that the I-cache & D-cache line sizes must be the same, as this is not necessarily true. If the cache sizes are defined by a configuration then they will be hardcoded as before, so this patch will not add overhead to such boards. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

* MIPS: mips32/cache.S: remove superfluous register assignmentGabor Juhos2013-07-24-2/+1
| | | | | | | | | | | | The t4 register already holds the cache line size, and the value of the register is not changed in mips_init_icache. Get the cache line size value from t4 for mips_init_dcache as well and remove the superfluous assignment of t5 register. Signed-off-by: Gabor Juhos <juhosg@openwrt.org>

| | | | | | | | | | Commit ab2a98b11716364bc5a8c43cdfa7fee176cda1d8 missed to use the new config option in dcache_enable(). Fix this to avoid inconsistencies if someone wants to disable and enable D-caches. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>
* MIPS: Coding style cleanups on common assembly filesShinya Kuribayashi2011-05-07-43/+38
| | | | | | | | | | Fix style issues and alignments globally. No logical changes. - Replace C comments with AS line comments where possible - Use ifndef where possible, rather than if !defined for simplicity - An instruction executed in a delay slot is now indicated by a leading space, not by C comment Signed-off-by: Shinya Kuribayashi <skuribay@pobox.com>
* MIPS: Remove mips_cache_lock() featureShinya Kuribayashi2011-05-07-93/+0
| | | | | | | | | As requested in commit e1390801a3c1a2b6d12fa90be368efc19f5b9bfd ([MIPS] Request for the 'mips_cache_lock()' removal), such feature is no longer needed for current MIPS implementation of U-Boot, and no one in the tree uses it for years.

* MIPS: Move content of arch/mips/cpu to arch/mips/cpu/mips32Daniel Schwierzeck2011-04-02-0/+328
All current CPUs and SoCs are based on MIPS32 arch. The complete code resides in the global arch/mips/cpu directory. This is not suitable if other MIPS architectures like MIPS64 or Octeon should be supported in the future. To achieve this the current CPU code is moved to its own mips32 subdirectory. All MIPS32 boards have to use mips32 as config switch in board.cfg.
