0ad7f0950a ppc4xx: cleanup default environment for AMCC boards
None of the AMCC boards uses an embedded environment, so there is no
need to run "saveenv" after updating U-Boot.  Drop the redundant
commands from the default environment.

f534c7cdc6 config.mk: avoid -traditional-cpp on OS X 10.5
Simply trying to include a basic header file like stdlib.h on OS X 10.5
and then building with -traditional-cpp fails with lots of errors like:
In file included from /usr/include/stdlib.h:63,
                 from test.c:3:
/usr/include/available.h:85: error: stray '#' in program
/usr/include/available.h:85: error: syntax error before numeric constant
/usr/include/available.h:86: error: stray '#' in program

In the past, I hadn't noticed because the old logic for these flags were
restricted to Darwin running on PowerPC systems while I'm running on an
Intel system.  But after some recent clean ups and changes, the flag was
being applied to all Darwin systems and my host tools broke.

3840ebfaf8 fdt: Fix bug in size calculation in fdt_resize() with initrd use
Original bug description from Feng (fdt_resize() bug caused "WARNING:
could not set linux, initrd-start FDT_ERR_NOSPACE."):

What I got is an error: "WARNING: could not set linux,initrd-start
FDT_ERR_NOSPACE." after loading Device Tree blob. This in turn caused
linux to miss init part.

After some digging, I found out the reason for this error, it is caused
by fdt_resize().

FDT blob got resized after filling in all board specific information of
PowerPC. (in boot_body_linux()). It reduced blob size with only extra
space for two fdt_reserve_entry, one for fdt itself, and one for initrd.
Then it's aligned to a 0x1000 page boundary. However, later in
fdt_initrd(), it could add two more properties, initrd-start AND
initrd-end, each one needs at least two fdt_reserve_entry sizes done by
_fdt_add_property() (name and value). Thus, the two fdt_reserve_entry
extra space is not sufficient.

So for some specific fdt size which is just under the page boundary
after resizing, this will cause an error of FDT_ERR_NOSPACE in
fdt_initrd() when setting those two properties, and failed to pass
initrd information to linux.

My fix is in fdt_resize(), leave at least 4 fdt_reserve_entry for
initrd. So instead of 2*sizeof(struct fdt_reserve_entry) for
actual_totalsize, use 5*sizeof(struc fdt_reserve_entry).

Stefan: I got this same error on katmai, when trying to boot with
initrd (run flash_self). This patch fixes this issue.

If a flash is unable to be detected, and then someone calls flash_protect

64419e4751 print_buffer: optimize & shrink
Applying a little creative format string allows us to shrink the initial
data read & display loop by only calling printf once.  Re-using the local
data buffer to generate the string we want to display then allows us to
output everything with just one printf call instead of multiple calls to
the putc function.

The local stack buffer needs increasing by 1 byte, but the resulting code
shrink and speed up is worth it I think.

No need to output spaces 1 char at a time in a loop when the printf code
can do the same thing with the right format string.  This shrinks things
and gives a nice speed up when killing off lines more than a byte or two
as printf will send out the buffer in one big chunk.

958e120643 fdt relocate: have more attention to use a bootmap or not
Platforms with flat device tree support can use a bootmap to relocate
the fdt_blob. This is not a must. That's why the relocation function
boot_relocate_fdt() should be use only if CONFIG_OF_LIBFDT was defined
together with CONFIG_SYS_BOOTMAPSZ (see common/cmd_bootm.c).

On MicroBlaze platforms there is no need to use a bootmap to relocate
a fdt blob. So we need a more precise focus on the compilation and usage
of boot_relocate_fdt().

In general it is valid to exclude the function boot_relocate_fdt() if
the bootmap size CONFIG_SYS_BOOTMAPSZ is not defined.

c519facc64 Fix condition where bootm_size not set and wrong memory size reported
If the user sets bootm_low and does not set bootm_size, u-boot will
report the memory node in the flat device tree incorrectly. Instead
of reporting the remaining size of memory, it will report the total
available memory which is incorrect.

Specifically this fixes the situation when booting a relocatable
kernel and the memory is reported as an offset and size in the
device tree, and the size needs to be adjusted accordingly.

cdb749778a Rename getenv_r() into getenv_f()
While running from flash, i. e. before relocation, we have only a
limited C runtime environment without writable data segment. In this
phase, some configurations (for example with environment in EEPROM)
must not use the normal getenv(), but a special function.  This
function had been called getenv_r(), with the idea that the "_r"
suffix would mean the same as in the _r_eentrant versions of some of
the C library functions (for example getdate vs. getdate_r, getgrent
vs. getgrent_r, etc.).

Unfortunately this was a misleading name, as in U-Boot the "_r"
generally means "running from RAM", i. e. _after_ relocation.

To avoid confusion, rename into getenv_f() [as "running from flash"]
