The kernel gets the ethernet MAC from the ethaddr variable, the omap boards for
devices with USB based eth adapters just set the usbethaddr which doesn't appear
to get passed to the kernel. The same Raspberry Pi code sets both ethaddr and
usbethaddr so lets do that so linux (tested 4.13 and 4.14) get a static rather
than a random MAC address, while not regressing users of usbethaddr.

When eMMC was formattaed for Linux partition table, "userdata" partition
is missing. In this case, part_get_info_by_name() iterates over all
registered drivers (which are PART_TYPE_EFI, PART_TYPE_DOS and
PART_TYPE_ISO). And when it comes to PART_TYPE_ISO (which has empty
partition table), we can see next warning in U-Boot output:
** First descriptor is NOT a primary desc on 1:1 **
This patch switches to part_get_info_by_name_type() API in order to
check only EFI partitions for "userdata" partitions. This eliminates
mentioned warning.

When using regular $partitions variable (for Linux boot), we can see
some unwanted messages:
> ERROR: cannot find partition: 'userdata'
> at arch/arm/mach-omap2/utils.c:96/omap_mmc_get_part_size()
> Warning: fastboot.userdata_size: unable to calc
Let's remove those, as missing 'userdata' partition is correct behavior
for Linux partition, and we don't want to see some Android-related
messages in this case.

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:
# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)
Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.
The semantic patch I used is as follows:
// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories. All refernces to the former locations are updated to
the current locations. For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.

Since there is a common function to grab the serial number from the die id bits,
it makes sense have one to parse that serial number and feed it to the serial
ATAG.

This patch populates serial number environment variable from
die_id_0 and die_id_1 register values for DRA7xx boards.
The function is added in omap common code so that this can be re-used.
Serial# environment variable will be useful to show correct
information in "fastboot devices" commands.

TI platforms such as OMAP5uevm, PandaBoard, use equivalent
logic to generate fake USB MAC address from device unique DIE ID.
Consolidate this to a generic location such that other TI platforms such
as BeagleBoard-XM can also use the same.
NOTE: at this point in time, I dont yet see a need for a generic dummy
ethernet MAC address creation function, but if there is a need in the
future, this can be further abstracted out.

Calculate EMIF register values based on AC timing parameters
from the SDRAM datasheet and the DDR frequency rather than
using the hard-coded values.
For a new board the user doen't have to go through the tedious
process of calculating the register values. Instead, just
provide the AC timings from the device data sheet as input
and the driver will automatically calculate the register values.

- Add a framework for layered cache maintenance
- separate out SOC specific outer cache maintenance from
maintenance of caches known to CPU
- Add generic ARMv7 cache maintenance operations that affect all
caches known to ARMv7 CPUs. For instance in Cortex-A8 these
opertions will affect both L1 and L2 caches. In Cortex-A9
these will affect only L1 cache
- D-cache operations supported:
- Invalidate entire D-cache
- Invalidate D-cache range
- Flush(clean & invalidate) entire D-cache
- Flush D-cache range
- I-cache operations supported:
- Invalidate entire I-cache
- Add maintenance functions for TLB, branch predictor array etc.
- Enable -march=armv7-a so that armv7 assembly instructions can be
used

Any custom xilinx ppc405 board can be added very easily with no code
duplicity.
This patch also adds a simple generic board, that can be used on almost
any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h
