Add support for KARO TX25 board

2010-03-07T18:36:36+00:00

This is an i.MX25 base board with only NAND
so it uses nand_spl to boot.

mpc83xx: fix out-of-tree mpc8315 nand build

2010-03-02T17:24:40+00:00

commit 2e95004deb6e33e33bf1b8a92a38cd2115bac4c2 "mpc83xx: Add NAND boot support
for MPC8315E-RDB boards" symlinked nand_spl/board/freescale/mpc8315erdb to
mpc8313erdb in order to not duplicate code.

Since the main makefile builds nand_spl/board/$(BOARDDIR) (which makes sense),
and the board Makefile and linker script are the only two necessary files
to enable out-of-tree building, and other boards have duplicated nand makefiles
(e.g. 8536ds & 8569mds), it only seems prudent to copy these two files in the
name of the 8315 too.

Add MX25 support to nand_spl fsl nfc driver

2010-01-27T20:22:41+00:00

MX25 has a different version of the fsl_nfc
flash controller known as version 1.1.

Add support to the nand_spl fsl_nfc driver

Versioning differs from mainline mxc kernel driver
no consensus yet on if the naming here and in
Redboot or the kernel is "correct".

ppc/85xx: Fix inclusion of 83xx immap in 85xx builds

2009-11-05T03:39:07+00:00

The nand_boot_fsl_elbc.c is shared between 83xx & 85xx however we should
not be including the immap_83xx.h when building 85xx.  We can just get
this all from common.h

NAND boot: MPC8536DS support

2009-09-30T13:42:06+00:00

MPC8536E can support booting from NAND flash which uses the
image u-boot-nand.bin. This image contains two parts: a 4K
NAND loader and a main U-Boot image. The former is appended
to the latter to produce u-boot-nand.bin. The 4K NAND loader
includes the corresponding nand_spl directory, along with the
code twisted by CONFIG_NAND_SPL. The main U-Boot image just
like a general U-Boot image except the parts that included by
CONFIG_SYS_RAMBOOT.

When power on, eLBC will automatically load from bank 0 the
4K NAND loader into the FCM buffer RAM where CPU can execute
the boot code directly. In the first stage, the NAND loader
copies itself to RAM or L2SRAM to free up the FCM buffer RAM,
then loads the main image from NAND flash to RAM or L2SRAM
and boot from it.

This patch implements the NAND loader to load the main image
into L2SRAM, so the main image can configure the RAM by using
SPD EEPROM. In the first stage, the NAND loader copies itself
to the second to last 4K address space, and uses the last 4K
address space as the initial RAM for stack.

Obviously, the size of L2SRAM shouldn't be less than the size
of the image used. If so, the workaround is to generate another
image that includes the code to configure the RAM by SPD and
load it to L2SRAM first, then relocate the main image to RAM
to boot up.
