2009-09-15Move __set/clear_bit from ubifs.h to bitops.hSimon Kagstrom
__set_bit and __clear_bit are defined in ubifs.h as well as in asm/include/bitops.h for some architectures. This patch moves the generic implementation to include/linux/bitops.h and uses that unless it's defined by the architecture. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
2009-09-02Blackfin: use scratch pad for exception stackMike Frysinger
If the memory layout pushes the stack out of the default DCPLB coverage, the exception handler may trigger a double fault by trying to push onto the uncovered stack. So handle the exception stack similar to the kernel by using the top of the scratch pad SRAM. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-02Blackfin: increase default console sizeMike Frysinger
The default console size indirectly applies to length of env vars, so a smaller length makes it hard to pass longer command lines to kernels. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-02Blackfin: change global data register from P5 to P3Robin Getz
Since the Blackfin ABI favors higher scratch registers by default, use the last scratch register (P3) for global data rather than the first (P5). This allows the compiler's register allocator to use higher number scratch P registers, which in turn better matches the Blackfin instruction set, which reduces the size of U-Boot by more than 1024 bytes...

2009-07-18Blackfin: add os log functionsMike Frysinger
Part of the mini Blackfin ABI with operating systems is that they can use 0x4f0-0x4f8 to pass log buffers to/from bootloaders. So add support to U-Boot for reading the log buffer. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-09asm-generic: Consolidate errno.h to asm-generic/errno.hMichal Simek
This patch use blackfin errno.h implementation which correspond Linux kernel one. MIPS implemetation is different that's why I keep it. I removed ppc_error_no.h from Marvell boards which was the same too. I have got ack from ppc40x, blackfin, arm, coldfire and avr custodians.

2009-06-14Blackfin: convert specific pre/post config headers to common methodMike Frysinger
The Blackfin port was using asm/blackfin-config-{pre,post}.h to setup common Blackfin board defines. The common method now is to use config.h, so convert blackfin-config-post.h to that. Rename the still Blackfin specific blackfin-config-pre.h to config-pre.h so the naming conventions at least line up. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-14Blackfin: new spibootldr commandMike Frysinger
Newer Blackfin parts can an on-chip ROM that can boot LDRs over SPI flashes, so add a new 'spibootldr' command to take advantage of it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-05-29Blackfin: fix if() logic in bootrom evt1 checkMike Frysinger
A missing set of parenthesis caused the silicon revision to apply only to the BF533 and not the BF531/BF532 variants. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-05-06Blackfin: fix booting with older bootroms (no EVT1)Mike Frysinger
When dropping jump block support, the assumption was that all bootroms supported entry point redirection via the EVT1 register. Unfortunately, this turned out to be incorrect for the oldest Blackfin parts (BF533-0.2 and older and BF561). No one really noticed earlier because these parts usually are booted by bypassing the bootrom entirely, and older BF533 parts are not supported at all (too many anomalies).

2009-04-02Blackfin: force all boards to HZ of 1000Mike Frysinger
Since the Blackfin timer code requires HZ to be 1000, barf on any board that tries to use a different value. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-03-24Blackfin: bf537-stamp: rewrite MAC-in-flash handlingMike Frysinger
Use the common net eth functions to setup the env/global data with the MAC address, and properly handle the case where CONFIG_SYS_NO_FLASH is defined. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-03-23Blackfin: drop SPORT_TX read helper macrosMike Frysinger
The SPORT_TX registers cannot be read (the hardware will trigger an error), so drop the read helper macros. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-02-10Add an architecture specific config.h for common definesKumar Gala
We have common defines that we duplicate in various ways. Having an arch specific config.h gives us a common location for those defines. Eventually we should be able to replace this when we have proper Kconfig support. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-02-05Blackfin: move default boot SPI CS to common codeMike Frysinger
Move the default SPI CS that we boot from into common code so that it can be used in other SPI drivers and environment settings. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-02-02Blackfin: only flag L1 instruction for DMA memcpyMike Frysinger
The performance difference from doing an 8 bit DMA memcpy vs an optimized core memcpy can be pretty big when you add in the overhead of setting up the MDMA registers, cache flushes, etc... So only use dma_memcpy() when we actually require it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-02-02Blackfin: rewrite cache handling functionsMike Frysinger
Take the cache flush functions from the kernel as they use hardware loops in order to get optimal performance. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-02-02Blackfin: cache core/system clock valuesMike Frysinger
Calculating the clocks requires a bit of calls to gcc math functions, so cache the values after the first run since they'll most likely never change once U-Boot is up and running. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-01-28Blackfin: fix dcache handling when doing dma memcpy'sMike Frysinger
Our dcache invalidate function doesn't just invalidate, it also flushes. So rename the function accordingly and fix the dma_memcpy() function so it doesn't inadvertently corrupt the data destination. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2008-12-15Introduce virt_to_phys()Kumar Gala
virt_to_phys() returns the physical address given a virtual. In most cases this will be just the input value as the vast majority of systems run in a 1:1 mode. However in systems that are not running this way it should report the physical address or ~0 if no mapping exists for the given virtual address. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
