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"]

952e7760bf ppc4xx: Convert PPC4xx UIC defines from lower case to upper case
The latest PPC4xx register cleanup patch missed the UIC defines.
This patch now changes lower case UIC defines to upper case.

d1c3b27525 ppc4xx: Big cleanup of PPC4xx defines
This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

de47a34d4d 4xx: Remove binary cpld bitstream from DP405 board
This patch removes the cpld binary bitstream that is
used by esd's cpld command on DP405 boards.

Because u-boot with an external cpld bitstream may not
take more space in flash than before the u-boot binary is
shrinked a little bit. Some unused featues have been
removed therefore.

bb57ad4be7 ppc4xx: Use correct io accessors for esd 405/440 boards
This patch replaces in/out8/16/32 macros by in/out_8/_be16/_be32
macros. Also volatile pointer references are replaced by the
new accessors.

97b0734d65 ppc4xx: Remove obsolete or unused functions from some esd boards
This patch removes initdram() and testdram() from most esd 405 platforms.
Some boards also have an empty dummy implementation of
misc_init_f(). This is also removed.

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.

c837dcb1a3 * The PS/2 mux on the BMS2003 board needs 450 ms after power on
before we can access it; add delay in case we are faster (with no
  CF card inserted)

* Cleanup of some init functions

* Make sure SCC Ethernet is always stopped by the time we boot Linux
  to avoid Linux crashes by early packets coming in.

* Accelerate flash accesses on LWMON board by using buffered writes
