TQM885D: Exchanged SDRAM timing by a more relaxed timing.
CAS-Latency=2, Write Recovery Time tWR=2
The max. supported bus frequency is 66 MHz. Therefore, changed
threshold to switch from 1:1 mode to 2:1 from 80 MHz to 66 MHz.

TQM885D: use calculated cpuclk instead of measuring it
On the TQM885D the measurement of cpuclk with the PIT reference
timer ist not necessary. Since all module variants use the same
external 10 MHz oscillator, the cpuclk only depends on the PLL
configuration - which is readable by software.

At 133 MHz the current SDRAM refresh rate is too fast
(measured 4 * 1.17 us).
CFG_MAMR_PTA changes from 39 to 128. This result
in a refresh rate of 4 * 7.8 us at the default clock
66 MHz. At 133 MHz the value will be then 4 * 3.8 us.
This is a compromise until a new method is found to
adjust the refresh rate.

Run fixups based on the JEDEC manufacturer ID independent of the
command set ID.
This changes current behaviour: Previously, geometry reversal for AMD
chips were done based on the command set ID, while they are now done
based on the JEDEC manufacturer and device ID.
Also add fixup for top-boot Atmel chips. A fixup is needed for
AT49BV6416(T) too, but since u-boot currently only reads the low byte
of the device ID, there's no way to tell it apart from AT49BV642D,
which should not have this fixup. Since AT49BV642D support is
necessary to get ATNGW100 board support into mainline, I've commented
out the fixup for now.
Move things like reading JEDEC IDs and fixing up geometry reversal
into separate functions. The geometry reversal fixup is now performed
by altering the qry structure directly, which makes the sector init
code slightly cleaner.
Read out the whole CFI Standard Query structure after successful cfi
identification. This allows subsequent code to access this information
directly without having to go through flash_read_uchar() and friends.
The timer code depends on the timer interrupt to keep track of the
upper 32 bits of the cycle counter. This obviously doesn't work when
interrupts are disabled the whole time.
Add all the ATSTK1000 daughterboards to MAINTAINERS along with their
"mother". Also update the entry for ATSTK1000 to be not only about the
AP7000 CPU; it's intended to handle all CPUs in the AT32AP family.
The SoC-specific code for all the AT32AP700x CPUs is practically
identical; the only difference is that some chips have less features
than others. By doing this rename, we can add support for the AP7000
derivatives simply by making some features conditional.
Use map_physmem() and unmap_physmem() to convert from physical to
virtual addresses. This gives the arch a chance to provide an uncached
mapping for flash accesses.
map_physmem() returns a virtual address which can be used to access a
given physical address without involving the cache. unmap_physmem()
should be called when the virtual address returned by map_physmem() is
no longer needed.
This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.
Introduce flash_read{8,16,32,64) and flash_write{8,16,32,64} and use
them to access the flash memory. This makes it clearer when the flash
is actually being accessed; merely dereferencing a volatile pointer
looks just like any other kind of access.
Implement __raw_{read,write}[bwl] on all architectures
This adds implementations of __raw_read[bwl] and __raw_write[bwl] to
m68k, ppc, nios and nios2. The m68k and ppc implementations were taken
from Linux.
cfi_flash: Reorder functions and eliminate extra prototypes
Reorder the functions in cfi_flash.c so that each function only uses
functions that have been defined before it. This allows the static
prototype declarations near the top to be eliminated and might allow
gcc to do a better job inlining functions.
This patch tries to keep all lines in the cfi_flash driver below 80
columns. There are a few lines left which don't fit this requirement
because I couldn't find any trivial way to break them (i.e. it would
take some restructuring, which I intend to do in a later patch.)
CFI: support JEDEC flash roms in CFI-flash framework
The following patch adds support for non-CFI flash ROMS, by hooking into the
CFI flash code and using most of its code, as recently discussed here in the

[BUILD] Remove libraries when updating autoconf.mk
Fix library problems caused by conditional compilation. Using
autoconf.mk to decide which files to compile has caused a problem when
changing configuration from one board to another without clearing out
the library (*.a) files.
It used to be that the linker was always passed the same list of .o
files when building the .a files. However, that is not longer true
with conditional compilation. Now, a different board config will have
a different file list passed to the linker. The problem occurs when
a library has already been built and the board config is changed.
Since the linker will update instead of replace a preexisting library,
then if the file list changes to remove some object files the old
objects will still exist in the library.
The solution is to remove all old library files when autoconf.mk is
made.

[BUILD] Generate include/autoconf.mk from board config files
Use cpp and sed to postprocess config.h and import the defined values
into include/autoconf.mk. autoconf.mk is then included by config.mk to

Doing this enables conditional compilation at the Makefile level instead
