c39f44dc6f powerpc/8xxx: Refactor fsl_ddr_get_spd into common code from board
Move fsl_ddr_get_spd into common mpc8xxx/ddr/main.c as most boards
pretty much do the same thing.  The only variations are in how many
controllers or DIMMs per controller exist.  To make this work we
standardize on the names of the SPD_EEPROM_ADDRESS defines based on the
use case of the board.

We allow boards to override get_spd to either do board specific fixups
to the SPD data or deal with any unique behavior of how the SPD eeproms
are wired up.

5df4b0ad0d powerpc/8xxx: Replace fsl_ddr_get_mem_data_rate with get_ddr_freq()
Every 85xx board implements fsl_ddr_get_mem_data_rate via get_ddr_freq()
and every 86xx board uses get_bus_freq().  If implement get_ddr_freq()
as a static inline to call get_bus_freq() we can remove
fsl_ddr_get_mem_data_rate altogether and just call get_ddr_freq()
directly.

eddf52b593 Replace "FLASH" strings with "Flash" or "flash"
There's no compelling reason to have the output on bootup or the
"flinfo" command print "flash" in uppercase, so use the proper case
where appropriate.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

c00ac259f6 xes: Make X-ES board names more generic
Some U-Boot images for X-ES boards support multiple products in the same
family.  For example, the XPedite5370, XPedite5371, and XPedite5372 are
similar enough that one U-Boot image can work on all 3 cards.  To make it
clear that a U-Boot image can work on boards of the same family, rename
the boards with the least significant digit of 'x'.

While we're at it, change the board config file and make targets to be
lowercase.

Also change the default uImage and fdt filenames to "board.uImage" and
"board.dtb" to be more generic.
