865ff85640 fsl: Change fsl_phy_enet_if to phy_interface_t
The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum.
This meant that drivers which used fsl_phy_enet_if to deal with
PHY interfaces would have to convert between the two (or we would have
to have them mirror each other, and deal with the ensuing maintenance
headache). Instead, we switch all clients of fsl_phy_enet_if over to
phy_interface_t, which should become the standard, anyway.

09c04c2096 Remove instances of phy_read/write
There were a few files which were already using phy_read and phy_write
for their PHY function names.  It's only a few places, and the name
seems most appropriate for the high-level abstraction, so let's
rename the other versions to something more specific.

Also, uec_phy.c had a marvell_init function which I renamed to not
conflict with the one in marvell.c

Lastly, uec_phy.c was putting a space between the phy writing
function names, and the open paren, so I fixed that

a52d2f816d powerpc/85xx: Add P1021 specific QE and UEC support
P1021 has some QE pins which need to be set in pmuxcr register before
using QE functions. In this patch, pin QE0 and QE3 are set for UCC1 and
UCC5 in Eth mode.  QE9 and QE12 are set for MII management. QE12 needs to
be released after MII access because QE12 pin is muxed with LBCTL signal.

Also added relevant QE support defines unique to P1021.

The P1021 QE is shared on P1012, P1016, and P1025.

8ef583a035 miiphy: convert to linux/mii.h
The include/miiphy.h header duplicates a lot of things from linux/mii.h.
So punt all the things that overlap to keep the API simple and to make
merging between U-Boot and Linux simpler.

c05b18fd77 Exclude drivers/qe/fdt.c without CONFIG_QE
Previously with archive libraries fdt.o was compiled and included in
qe.a and then discarded by the linker.  With partial linking this
results in unresolved symbols, which this commit fixes.

This commit also cleans up a now-useless conditional in fdt.c.

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.

47e26b1bf9 cmd_usage(): simplify return code handling
Lots of code use this construct:

	cmd_usage(cmdtp);
	return 1;

Change cmd_usage() let it return 1 - then we can replace all these
ocurrances by

	return cmd_usage(cmdtp);

This fixes a few places with incorrect return code handling, too.

54841ab50c Make sure that argv[] argument pointers are not modified.
The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands.  Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".

This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:

int main (int argc, char **argv)
{
	while (--argc > 0 && **++argv == '-') {
/* ====> */	while (*++*argv) {
			switch (**argv) {
			case 'd':
				debug++;
				break;
			...
			default:
				usage ();
			}
		}
	}
	...
}

The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell.  With the modification, the compiler will prevent this with
an
	error: increment of read-only location '*argv'

N.B.: The code above can be trivially rewritten like this:

	while (--argc > 0 && **++argv == '-') {
		char *arg = *argv;
		while (*++arg) {
			switch (*arg) {
			...

a47a12becf Move arch/ppc to arch/powerpc
As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.

Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

582c55a027 83xx, uec: split enet_interface in two variables
There's no sensible reason to unite speed and interface type into
one variable.  So split this variable enet_interface into two
vars: enet_interface_type, which hold the interface type and speed.

Also: add the possibility for switching between 10 and 100 MBit
interfaces on the fly, when running in FAST_ETH mode.

1443cd7e54 UEC FIXED PHY: Determine fixed-phy port using UEC interface name.
Fixed a misunderstanding in the original implementation, 'devnum' that
was used in the cpu/ppc4xx/4xx_enet.c implementation was NOT the
PHY's SMI address, rather it was the number of the MAC interface on
the CPU. The equivalent of this for uec_phy will be the UEC number
stored in mii_info->dev->name. Usage example is updated for uec.

It is set to 0x1F by default and can be overwritten on the board
header file by defining CONFIG_UTBIPAR_INIT_TBIPA. This allows
the CPU to simply "reserve" one SMI address instead of using
a different one for each UEC.
