b4fe1a7109 MPC8360ERDK: adapt NAND interface for the re-written FSL NAND UPM driver
This patch is based on the following patch sent a few minutes ago:
"NAND FSL UPM: driver re-write using the hwcontrol callback"
It is untested, of course. Anton, could you please give it a try.

fb8c061ea0 cfi-flash: Fix problem in flash_toggle(), busy was not detected reliably
This patch simplifies flash_toggle() (AMD commandset), which is used to
detect if a FLASH device is still busy with erase/program operations. On
800MHz Canyonlands/Glacier boards (460EX/GT) the current implementation
did not detect the busy state reliably, resulting in non erased sectors
etc. This patch now simplifies this function by "just" comparing the
complete data-word instead of ANDing it with the command-word (0x40)
before the compatison. It is done the same way in the Linux implementation
chip_ready() in cfi_cmdset_0002.c.

212ed90615 ppc4xx: Canyonlands: Disable the RTC M41T62 square wave output
This patch disables the square wave output of the M41T62 RTC used on
Canyonlands & Glacier. Here the explanation:

The serial real-time clock part used in the design is an
STMicro M41T62. This part has a full-time 32KHz square wave
output that is connected to the TmrClk input to the
processor. The default state for this square wave output is
enabled so the output runs continuously when the board is
powered normally and also from the battery. The TmrClk input
to the processor goes to ground when the power is removed
from the board/processor, and therefore the running square
wave output is driving ground which drains the battery quickly.

Date:   Fri Jun 6 14:28:14 2008 +0200

    tools/mkimage: fix compiler warnings on some systems.

Broke building on some systems, because the host's string.h was interfering
with u-boot's linux/string.h.  It doesn't look like we need the u-boot one if
we're building for the host, so now we only include when building inside
u-boot.

9973e3c614 Change initdram() return type to phys_size_t
This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory.  phys_size_t is defined as an unsigned long on almost
all current platforms.

This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram).  It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.

Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

b57ca3e128 Change bd/gd memsize/ram_size to be phys_size_t.
Currently, both are defined as an unsigned long, but
should be phys_size_t. This should result in no real change,
since phys_size_t is currently an unsigned long for all the
default configs.  Also add print_lnum to cmd_bdinfo to deal
with the potentially wider memsize.

e8cc3f04b1 TQM85xx: Change memory map to support Flash memory > 128 MiB
Some TQM85xx boards could be equipped with up to 1 GiB (NOR) Flash
memory. The current memory map only supports up to 128 MiB Flash.
This patch adds the configuration option CONFIG_TQM_BIGFLASH. If
set, up to 1 GiB flash is supported. To achieve this, the memory
map has to be adjusted in great parts (for example the CCSRBAR is
moved from 0xE0000000 to 0xA0000000).

If you want to boot Linux with CONFIG_TQM_BIGFLASH set, the new
memory map also has to be considered in the kernel (changed
CCSRBAR address, changed PCI IO base address, ...). Please use
an appropriate Flat Device Tree blob (tqm8548.dtb).

1c2deff22c TQM85xx: NAND support via local bus UPMB
This patch adds support for NAND FLASH on the TQM8548. It is disabled by
default and can be enabled for the TQM8548 modules. It is now based on
the re-written FSL NAND UPM driver. A patch has been posted earlier today
with the subject:

"NAND FSL UPM: driver re-write using the hwcontrol callback"

Note that the R/B pin is not supported by that module requiring to use
the specified maximum delay time.

Note: With NAND support enabled the size of the U-Boot image exceeds
256 KB and TEXT_BASE must therefore be set to 0xfff80000 in config.mk,
doubling the image size :-(.

a75a57ef6e NAND FSL UPM: driver re-write using the hwcontrol callback
This is a re-write of the NAND FSL UPM driver using the more universal
hwcontrol callback (instead of the cmdfunc callback). Here is a brief
list of furher modifications:

- For the time being, the UPM setup writing the UPM array has been
  removed from the driver and must now be done by the board specific
  code.

- The bus width definition in "struct fsl_upm_nand" is now in bits to
  comply with the corresponding Linux driver and 8, 16 and 32 bit
  accesses are supported.

- chip->dev_read is only set if fun->dev_ready != NULL, which is
  required for boards not connecting the R/B pin.

- A few issue have been fixed with MxMR bit manipulation like in the
  corresponding Linux driver.

Note: I think the "io_addr" field of "struct fsl_upm" could be removed
      as well, because the address is already determined by
      "nand->IO_ADDR_[RW]", but I'm not 100% sure.

This patch has been tested on a TQM8548 modules with the NAND chip
Micron MT29F8G08FABWP.

This patch is based on the following patches posted to this list a few
minutes ago:

  PPC: add accessor macros to clear and set bits in one shot
