powerpc: Fix bootm to boot up again with a Ramdisk

2008-09-13T00:03:38+00:00

Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.

When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.

I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

fdt: refactor initrd related code

2008-08-26T21:45:20+00:00

Created a new fdt_initrd() to deal with setting the initrd properties
in the device tree and fixing up the mem reserve.  We can use this
both in the choosen node handling and lets us remove some duplicated
code when we fixup the initrd info in bootm on PPC.

bootm: Set working fdt address as part of the bootm flow

2008-08-26T21:37:54+00:00

Set the fdt working address so "fdt FOO" commands can be used as part
of the bootm flow.  Also set an the environment variable "fdtaddr"
with the value.

fdt: rework fdt_fixup_ethernet() to use env instead of bd_t

2008-08-21T00:07:43+00:00

Move to using the environment variables 'ethaddr', 'eth1addr', etc..
instead of bd->bi_enetaddr, bi_enet1addr, etc.

This makes the code a bit more flexible to the number of ethernet
interfaces.

fdt: add crypto node handling for MPC8{3, 5}xxE processors

2008-07-14T22:01:29+00:00

Delete the crypto node if not on an E-processor.  If on 8360 or 834x family,
check rev and up-rev crypto node (to SEC rev. 2.4 property values)
if on an 'EA' processor, e.g. MPC8349EA.

83xx/fdt_support: let user specifiy FSL USB Dual-Role controller role

2008-03-26T00:19:39+00:00

Linux understands "host" (default), "peripheral" and "otg" (broken).
Though, U-Boot doesn't restrict dr_mode variable to these values (think
of renames in future).

Remove deprecated CONFIG_OF_HAS_UBOOT_ENV and CONFIG_OF_HAS_BD_T

2008-03-25T23:22:39+00:00

These defines embedded the u-boot env variables and/or the bd_t structure
in the fdt blob.  The conclusion of discussion on the u-boot email list
was that embedding these in the fdt blob is not useful: there are better
ways of passing the data (in fact, the fdt blob itself replaces the
bd_t struct).

The only board that enables these is the stxxtc and they don't appear
to be used by linux.

85xx: add ability to upload QE firmware

2008-01-09T22:28:12+00:00

Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it.  Add function qe_upload_firmware() to parse the blob and
perform the actual upload.  Add command-line command "qe fw" to take a firmware
blob in memory and upload it.  Update ft_cpu_setup() on 85xx to create the
'firmware' device tree node if U-Boot has uploaded a firmware.  Fully define
'struct rsp' in immap_qe.h to include the actual RISC Special Registers.

Add fdt_find_and_setprop() to fdt_support.h

2008-01-08T20:03:06+00:00

fdt_find_and_setprop() is used by several 4xx boards and it's
missing in the appropriate header. This patch eliminates a
warning when building U-Boot for such boards.
