* Blackfin: use scratch pad for exception stackMike Frysinger2009-09-02-0/+4
| | | | | | | | | 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>
* Blackfin: increase default console sizeMike Frysinger2009-09-02-5/+1
| | | | | | | 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>
* Blackfin: change global data register from P5 to P3Robin Getz2009-09-02-1/+1
| | | | | | | | | | | 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...

* Blackfin: add os log functionsMike Frysinger2009-07-18-0/+3
| | | | | | | | 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>
* asm-generic: Consolidate errno.h to asm-generic/errno.hMichal Simek2009-07-09-156/+1
| | | | | | | | | | | | | | | 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.

* Blackfin: convert specific pre/post config headers to common methodMike Frysinger2009-06-14-168/+144
| | | | | | | | | | 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>
* Blackfin: new spibootldr commandMike Frysinger2009-06-14-0/+27
| | | | | | | 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>
* Blackfin: fix if() logic in bootrom evt1 checkMike Frysinger2009-05-29-1/+1
| | | | | | | 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>
* Blackfin: fix booting with older bootroms (no EVT1)Mike Frysinger2009-05-06-0/+8
| | | | | | | | | | | 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).

* Blackfin: force all boards to HZ of 1000Mike Frysinger2009-04-02-2/+6
| | | | | | | 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>
* Blackfin: bf537-stamp: rewrite MAC-in-flash handlingMike Frysinger2009-03-24-0/+28
| | | | | | | 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>

* Blackfin: drop SPORT_TX read helper macrosMike Frysinger2009-03-23-26/+0
| | | | | | | 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>

* Add an architecture specific config.h for common definesKumar Gala2009-02-10-0/+24
| | | | | | | | | | 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>

* Blackfin: only flag L1 instruction for DMA memcpyMike Frysinger2009-02-02-10/+4
| | | | | | | | | 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>
* Blackfin: rewrite cache handling functionsMike Frysinger2009-02-02-0/+4
| | | | | | | 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>
* Blackfin: cache core/system clock valuesMike Frysinger2009-02-02-0/+2
| | | | | | | | 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>

* Blackfin: fix dcache handling when doing dma memcpy'sMike Frysinger2009-01-28-1/+1
| | | | | | | | 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>

* Introduce virt_to_phys()Kumar Gala2008-12-15-0/+5
| | | | | | | | | | | | 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>

* Change bd/gd memsize/ram_size to be phys_size_t.Becky Bruce2008-06-12-2/+2
| | | | | | | | | | Currently, both are defined as an unsigned long, but should be phys_size_t. This should result in no real change, since phys_size_t is currently an unsigned long for all the default configs. Also add print_lnum to cmd_bdinfo to deal with the potentially wider memsize.
