DaVinci: Improve DaVinci SPI speed.
I have updated this patch based on the comments [1] by Wolfgang Denk and
removed unused variables.
[1][http://lists.denx.de/pipermail/u-boot/2010-May/071728.html]
Reduce the number of reads per byte transferred on the BUF register from 2 to 1 and
take advantage of the TX buffer in the SPI module. On LogicPD OMAP-L138 EVM,
SPI read throughput goes up from ~0.8Mbyte/s to ~1.3Mbyte/s. Tested with a 2Mbyte image file.
Remove unused variables in the spi_xfer() function.
Consolidated SDRC related functions into one file - sdrc.c
And also replaced sdrc_init with generic memory init
function (mem_init), this generalization of omap memory setup
is necessary to support the new emif4 interface introduced in AM3517.
TNETV107X is a Texas Instruments SoC based on an ARM1176 core, and with a
bunch on on-chip integrated peripherals. This patch adds support for the
TNETV107X EVM board.
TNETV107X is a Texas Instruments SoC based on an ARM1176 core, and with a
bunch on on-chip integrated peripherals. This is an initial commit with
basic functionality, more commits with drivers, etc. to follow.
The current ARM1176 CPU specific code is too specific to the SMDK6400
architecture. The following changes were necessary prerequisites for the
addition of other SoCs based on ARM1176.
Existing board's (SMDK6400) configuration has been modified to keep behavior
unchanged despite these changes.
1. Peripheral port remap configurability
The earlier code had hardcoded remap values specific to s3c64xx in start.S.
This change makes the peripheral port remap addresses and sizes configurable.
2. U-Boot code relocation support
Most architectures allow u-boot code to run initially at a different
address (possibly in NOR) and then get relocated to its final resting place
in RAM. Added support for this capability in ARM1176 architecture.
3. Disable TCM if necessary
If a ROM based bootloader happened to have initialized TCM, we disable it here
to keep things sane.
4. Remove unnecessary SoC specific includes
ARM1176 code does not really need this SoC specific include. The presence
of this include prevents builds on other ARM1176 archs.
5. Modified virt-to-phys conversion during MMU disable
The original MMU disable code masks out too many bits from the load address
when it tries to figure out the physical address of the jump target label.
Consequently, it ends up branching to the wrong address after disabling the
MMU.
Add the new board PM9G45 from Ronetix GmbH.
* AT91SAM9G45 MCU at 400Mhz.
* 128MB DDR2 SDRAM
* 256MB NAND
* 10/100 MBits Ethernet DP83848
* Serial number chip DS2401
The board is made as SODIMM200 module.

ARM1136: Fix cache_flush() error and correct cpu_init_crit() comments
The ARM1136 cache_flush() function uses the "mcr p15, 0, rn, c7, c7, 0"

is to clean and invalidate all caches. So add an "mcr p15, 0, %0, c7,

compiler.h: add uint typedef

x86: Provide weak PC/AT compatibility setup function
It is possibly to setup x86 boards to use non-PC/AT configurations. For
example, the sc520 is an x86 CPU with PC/AT and non-PC/AT peripherals.
This function allows the board to set itself up for maximum PC/AT
compatibility just before booting the Linux kernel (the Linux kernel
'just works' if everything is PC/AT compliant)
The x86 architecture exclusively uses Port-Mapped I/O (inb/outb) to access
the 16550 UARTs. This patch mimics how Linux selects between Memory-Mapped
and Port-Mapped I/O. This allows x86 boards to use CONFIG_SERIAL_MUTLI and
drop the custom serial port driver
Currently, the GDT is either located in FLASH or in the non-relocated
U-Boot image in RAM. Both of these locations are unsafe as those
locations can be erased during a U-Boot update. Move the GDT into the
highest available memory location and relocate U-Boot to just below it
Add a parameter to the 32-bit entry to indicate if entry is from Real
Mode or not. If entry is from Real Mode, execute the destructive 'sizer'
routine to determine memory size as we are booting cold and running in
Flash. If not entering from Real Mode, we are executing a U-Boot image
from RAM and therefore the memory size is already known (and running
'sizer' will destroy the running image)
There are now two 32-bit entry points. The first is the 'in RAM' entry
point which exists at the start of the U-Boot binary image. As such,
you can load u-boot.bin in RAM and jump directly to the load address
without needing to calculate any offsets. The second entry point is
used by the real-to-protected mode switch
This patch also changes TEXT_BASE to 0x6000000 (in RAM). You can load
the resulting image at 0x6000000 and simple go 0x6000000 from the u-boot
prompt
Hopefully a later patch will completely elliminate any dependency on
TEXT_BASE like a relocatable linux kernel (perfect world)
This patch allows the low-level assembler boot-strap to obtain the RAM
size without calling the destructive 'sizer' routine. This allows
boot-strapping from a U-Boot image loaded in RAM
There is an error in how the assembler version of the sc520 memory size
reporting code works. As a result, it will only ever report at most the
size of one bank of RAM
