Blackfin: disable syscontrol code for now

2009-02-22T00:23:20+00:00

Looks like the initcode updates fell out of order during my merges.  The
patch that really fixes up this code is part of power-on overhaul and so
is too large for merging at this point.  Instead, we can disable the code
as no currently in-tree board depends on it.  The next merge window will
fix things up properly.

Blackfin: dynamically update UART speed when initializing

2009-02-06T02:25:35+00:00

Previously, booting over the UART required the baud rate to be known ahead
of time.  Using a bit of tricky simple math, we can calculate the new board
rate based on the old divisors.

Blackfin: add support for fast SPI reads with Boot ROM

2009-02-06T02:25:35+00:00

Newer Blackfin boot roms support using the fast SPI read command rather than
just the slow one.  If the functionality is available, then use it.

Blackfin: check for reserved settings in DDR MMRs

2009-02-06T02:25:35+00:00

Some bits of the DDR MMRs should not be set.  If they do, bad things may
happen (like random failures or hardware destruction).

Blackfin: use on-chip syscontrol() rom function when available

2009-02-06T02:25:28+00:00

Newer Blackfin's have an on-chip rom with a syscontrol() function that needs
to be used to properly program the memory and voltage settings as it will
include (possibly critical) factory tested bias values.

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: enable --gc-sections

Start building all Blackfin boards with -ffunction-sections/-fdata-sections
and linking with --gc-sections.
