This patch depends on the previous two patches, introducing the
CONFIG_FLASH_SPANSION_S29WS_N and CONFIG_ARP_TIMEOUT configuration
options. It allows U-Boot to use buffered writes to the Spansion NOR flash
installed on this board, and eliminates long delays in network transfers
after the board startup.
Also modify flash layout to embed main and redundant environment blocks in
the U-Boot image.
cfi_flash: Support buffered writes on non-standard Spansion NOR flash
Some NOR flash chip from Spansion, for example, the s29ws-n MirrorBit
series require different addresses for buffered write commands. Define a
configuration option to support buffered writes on those chips. A more
elegant solution would be to automatically detect those chips by parsing
their CFI records, but that would require introduction of a fixup table
into the cfi_flash driver.
Currently the timeout waiting for an ARP reply is hard set to 5 seconds.
On i.MX31ADS due to a hardware "strangeness" up to four first IP packets
to the boards get lost, which typically are ARP replies. By configuring
the timeout to a lower value we significantly improve the first network
transfer time on this board. The timeout is specified in milliseconds,
later internally it is converted to deciseconds, because it has to be
converted to hardware ticks, and CFG_HZ ranges from 900 to 27000000 on
different boards.
Support for the MX31ADS evaluation board from Freescale
This patch adds support for the MX31ADS evaluation board from Freescale,
initialization code is copied from RedBoot sources, also provided by
Freescale.

Add setup_c0_status from Linux. For the moment we disable interrupts, set
CU0, mark the kernel mode, and clear ERL and EXL. This is good enough for
reset-time configuration and will work well across most processors.
We do Hit_Writeback_Inv_D and Hit_Invalidate_I. You might think that you
don't need to do Hit_Invalidate_I, but flush_cache() needs it since this
function is used not only in U-Boot specfic programs but also at loading
target binaries.
Currently we do 1) Index_Store_Tag_I, 2) Fill and 3) Index_Store_Tag_I
again per a loop for I-cache initialization. But according to 'See MIPS
Run', we're encouraged to use three separate loops rather than combining
them *for both I- and D-cache*. This patch tries to fix this.
In accordance with fixing above, mips_init_[id]cache are separated from
mips_cache_reset(), and rewrite cache loops are completely rewritten with
useful macros.
This patch replaces the current function definitions with NESTED, LEAF
and END macro. They specify some more additional information about the
function; an alignment of symbol, type of symbol, stack frame usage, etc.
These information explicitly tells the assembler and the debugger about
the types of code we want to generate.
[MIPS] Request for the 'mips_cache_lock()' removal
The initial intension of having mips_cache_lock() was to use the cache
as memory for temporary stack use so that a C environment can be set up
as early as possible.
But now mips_cache_lock() follow lowlevel_init(). We've already have the
real memory initilaized at this point, therefore we could/should use it.
No reason to lock at all.
Other problems:
Cache locking is not consistent across MIPS implementaions. Some imple-
mentations don't support locking at all. The style of locking varies -
some support per line locking, others per way, etc. Some parts use bits
in status registers instead of cache ops. Current mips_cache_lock() is
not necessarily general-purpose.
And this is worthy of special mention; once U-Boot/MIPS locks the lines,
they are never get unlocked, so the code relies on whatever gets loaded
after U-Boot to re-initialize the cache and clear the locks. We're sup-
posed to have CFG_INIT_RAM_LOCK and unlock_ram_in_cache() implemented,
but leave the situation as it is for a long time.
For these reasons, I proposed the removal of mips_cache_lock() from the
global start-up code.
This patch adds CFG_INIT_RAM_LOCK_MIPS to make existing users aware that
*things have changed*. If he wants the same behavior as before, he needs
to have CFG_INIT_RAM_LOCK_MIPS in his config file.
If we don't have any regression report through several releases, then
we'll remove codes entirely.
