The editenv command can be used to edit an environment variable.
Editing an environment variable is useful when one wants to tweak an
existing variable, for example fix a typo or change the baudrate in the
'bootargs' environment variable.Signed-off-by: Peter Tyser
-
Previously setenv() would only delete an environment variable if it
was passed a NULL string pointer as a value. It should also delete an
environment variable when it encounters a valid string pointer of
0-length.This change/fix is generally useful and is necessary for the upcoming
"editenv" command.Signed-off-by: Peter Tyser
-
If the 'buf' parameter is a non-0-length string, its contents will be
edited. Previously, the initial contents of 'buf' were ignored and the
user entered its contents from scratch.This change is necessary to support the upcoming "editenv" command but
could also be used for future commands which require a user to modify
an existing string.Signed-off-by: Peter Tyser

Previously, passing readline() or readline_into_buffer() a NULL 'prompt'
parameter would result in puts() printing garbage when
CONFIG_CMDLINE_EDITING was enabled.Note that no board currently triggers this bug. Enabling
CONFIG_CMDLINE_EDITING on some boards (eg bab7xx) would result in
the bug appearing. This change is only intended to prevent someone
from running into this issue in the future.Signed-off-by: Peter Tyser

Setup QE pin multiplexing for USB function, configure needed BCSRs
and add some fdt fixups.Signed-off-by: Anton Vorontsov
Signed-off-by: Kumar Gala -
To make QE UART usable by Linux we should setup pin multiplexing
and turn UCC2 Ethernet node into UCC2 QE UART node.Also, QE UART is mutually exclusive with UART0, so we can't enable
it if eSDHC is in 4-bits mode on pilot boards, or if it's a prototype
board with eSDHC in 1- or 4-bits mode.Signed-off-by: Anton Vorontsov

Signed-off-by: Kumar Gala -
eSDHC is mutually exlusive with UART0 (in 4-bits mode) and I2C2
(in 1-bit mode). When eSDHC is used, we should switch u-boot console to
UART1, and make the proper device-tree fixups.Because of an erratum in prototype boards it is impossible to use eSDHC
without disabling UART0 (which makes it quite easy to 'brick' the board
by simply issung 'setenv hwconfig esdhc', and not able to interact with
U-Boot anylonger).So, but default we assume that the board is a prototype, which is a most
safe assumption. There is no way to determine board revision from a
register, so we use hwconfig.Signed-off-by: Anton Vorontsov

This change has 3 goals:
- Have secondary cores be released into spin loops at their 'true'
address in SDRAM. Previously, secondary cores were put into spin
loops in the 0xfffffxxx address range which required that boot page
translation was always enabled while cores were in their spin loops.- Allow the TLB window that the primary core uses to access the
secondary cores boot page to be placed at any address. Previously, a
TLB window at 0xfffff000 was always used to access the seconary cores'
boot page. This TLB address requirement overlapped with other
peripherals on some boards (eg XPedite5370). By default, the boot
page TLB will still use the 0xfffffxxx address range, but this can be
overridden on a board-by-board basis by defining a custom
CONFIG_BPTR_VIRT_ADDR. Note that the TLB used to map the boot page
remains in use while U-Boot executes. Previously it was only
temporarily used, then restored to its initial value.- Allow Boot Page Translation to be disabled on bootup. Previously,
Boot Page Translation was always left enabled after secondary cores
were brought out of reset. This caused the 0xfffffxxx address range
to somewhat "magically" be translated to an address in SDRAM. Some
boards may not want this oddity in their memory map, so defining
CONFIG_MPC8xxx_DISABLE_BPTR will turn off Boot Page Translation after
the secondary cores are initialized.These changes are only applicable to 85xx boards with CONFIG_MP defined.

Currently fdt_fixup_stdout() is using hard-coded CONFIG_CONS_INDEX
constant. With multi-serial support, the CONS_INDEX may no longer
represent actual console, so we should try to extract port number
from the current stdio device name instead of always hard-coding the
constant value.Signed-off-by: Anton Vorontsov

Its possible that we end up with a device tree that happens to be a
particular size that after we call fdt_resize() we don't have any
space left for the initrd mem_rsv.Fix this be adding a second mem_rsv into the size calculation. We
had one to cover the fdt itself and we have the potential of adding
a second for the initrd.Signed-off-by: Kumar Gala

U-boot for Marvell Kirkwood boards no longer work after the EABI changes
introduced in commit f772acf8a584067033eff1e231fcd1fb3a00d3d9. This
turns out to be caused by a stack alignment issue. The armv5te
instructions ldrd/strd instructions require 8-byte alignment to work
properly (otherwise undefined behavior).Tested on an OpenRD base board, where both printouts and ubifs stuff now
works.Signed-off-by: Simon Kagstrom
