d87a2ad108 powerpc/mpc85xx: Remove some dead code
U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code.  It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.

The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).

Also remove a few other small unused functions.

96d2bb952b powerpc/mpc85xx: Don't relocate exception vectors
Booke does not require exception vectors to be located at address zero.
U-Boot was doing so anyway, simply because that's how it had been done
on other PPC.  The downside of this is that once the OS is loaded to
address zero, the exception vectors have been overwritten -- which
makes it difficult to diagnose a crash that happens after that point.

The IVOR setup and trap entry code is simplified somewhat as a result.

Also, there is no longer a need to align individual exceptions on 0x100
byte boundaries.

1fd92db83d net: cosmetic: Fix var naming net <-> eth drivers
Update the naming convention used in the network stack functions and
variables that Ethernet drivers use to interact with it.

This cleans up the temporary hacks that were added to this interface
along with the DM support.

This patch has a few remaining checkpatch.pl failures that would be out
of the scope of this patch to fix (drivers that are in gross violation
of checkpatch.pl).

58d423b88e dm: select CONFIG_DM* options
As mentioned in the previous commit, adding default values in each
Kconfig causes problems because it does not co-exist with the
"depends on" syntax.  (Please note this is not a bug of Kconfig.)
We should not do so unless we have a special reason.  Actually,
for CONFIG_DM*, we have no good reason to do so.

Generally, CONFIG_DM is not a user-configurable option.  Once we
convert a driver into Driver Model, the board only works with Driver
Model, i.e. CONFIG_DM must be always enabled for that board.
So, using "select DM" is more suitable rather than allowing users to
modify it.  Another good thing is, Kconfig warns unmet dependencies
for "select" syntax, so we easily notice bugs.

Actually, CONFIG_DM and other related options have been added
without consistency: some into arch/*/Kconfig, some into
board/*/Kconfig, and some into configs/*_defconfig.

This commit prefers "select" and cleans up the following issues.

[1] Never use "CONFIG_DM=n" in defconfig files

It is really rare to add "CONFIG_FOO=n" to disable CONFIG options.
It is more common to use "# CONFIG_FOO is not set".  But here, we
do not even have to do it.
Less than half of OMAP3 boards have been converted to Driver Model.
Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is
weird.  Instead, add "select DM" only to appropriate boards, which
eventually eliminates "CONFIG_DM=n", etc.

[2] Delete redundant CONFIGs

Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again
in configs/sandbox_defconfig.
Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and
defines it also in omap3_beagle_defconfig and devkit8000_defconfig.

since this number has increased (enum srds_prtcl has more

of all the configured protocols.
This patch replaces the u64 map values with static arrays.
To keep track of the number of serdes protocols, the
SERDES_PRCTL_COUNT vale has been added at the end of
enum srds_prtcl. This value must always be the last one.

d67be7c965 powerpc: mpc85xx: Add dummy gpio.h to enable CONFIG_OF_CONTROL
If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled.
It includes <asm/gpio.h> and then <asm/gpio.h> includes
<asm/arch/gpio.h>.  As a result, all the SoCs that enable
CONFIG_OF_CONTROL must have <asm/arch/gpio.h>.

The right fix would be to split the lib/fdtdec.c to remove
dependency on GPIO.

This commit adds a dummy <asm/arch/gpio.h> to support OF_CONTROL
for mpc85xx platform. A file mpc85xx_gpio.h exists in
arch/powerpc/include/asm. The defintions in that file conflict
with the ones in asm-generic/gpio.h. Hence a dummy header file
has been added. This will be removed after FDT-GPIO stuff is
fixed correctly.
