Blackfin: output booting source when booting

2009-02-02T17:27:16+00:00

Knowing the booting source of the part is useful, especially when the part
can switch dynamically between sources.

Blackfin: use 8/16/32 bit transfer widths in dma_memcpy()

2009-02-02T17:24:46+00:00

Rather than using 8bit transfers for everything, use 8/16/32 bit transfers
as usable with the source/destination addresses and the count size.

Blackfin: dma_memcpy(): fix random failures

2009-02-02T17:24:46+00:00

We have to make sure the DMA channel is actually disabled in hardware before
attempting to reprogram it.  Otherwise the new settings are ignored and we
end up with random hangs/failures.

Blackfin: rewrite cache handling functions

2009-02-02T17:24:44+00:00

Take the cache flush functions from the kernel as they use hardware loops in
order to get optimal performance.

Blackfin: setup bi_enetaddr for single nets

2009-02-02T17:24:43+00:00

For systems with CONFIG_NET_MULTI disabled, bi_enetaddr does not get setup
based on $ethaddr, so set it up.

Blackfin: cache core/system clock values

2009-02-02T17:24:42+00:00

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.

Blackfin: only build post code when CONFIG_POST

2009-02-02T17:24:30+00:00

Save some time by using CONFIG_POST in the Makefile rather than C files.

Blackfin: fixup misc warnings such as printf's and missing casts

Blackfin: pass RETX to Linux

2009-01-28T18:26:15+00:00

Make sure we save the value of RETX at power on and then pass it on to the
kernel so that it can nicely debug a "double-fault-caused-a-reset" crash.

Blackfin: respect CONFIG_SYS_MONITOR_LEN for default flash protection

2009-01-28T18:26:12+00:00

Respect the CONFIG_SYS_MONITOR_LEN define rather than assuming a size of
128kB when setting up the default flash protection region for U-Boot
itself.
