Blackfin: print out Flash: before checking it

2009-03-23T19:14:53+00:00

If there is some problem in the flash init/checking code, it's nicer to see
the message "Flash:" before crashing.  This way the source of the problem
is a bit more straightforward.

Blackfin: bfin_mac: force boards to setup the MAC themselves

2009-03-20T21:39:09+00:00

Since the on-chip MAC does not have an eeprom or similar interface, force
all Blackfin boards that use this driver to setup the board data with a
proper MAC.

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.
