757cd149b9 rpi: set board serial number in environment
Gets propagated into the device tree and then into /proc/cpuinfo where
users often expect it.

859f143715 rpi: set ethaddr as well
Let's set "ethaddr" when we get the ethernet address too, so that
fdt_fixup_ethernet() sets the address in the device tree and the Linux
driver can pick it up.

7443a9c405 rpi: fix up Model B entries
The P5 header was not present on "Model B" any board prior to Revision 2.0,
there's no need for a separate device tree.

Also, it looks like "rev2" is incorrectly used to only cover the 512MiB
memory models; there also were 256MiB 2.0 boards.

I don't have all of the boards to check this, I'm following this table:

dba060ce06 rpi: link to another model number info source
This source has been blessed by Dom Cobley at the RPi Foundation, so seems
like the best source to refer to. It's a superset of and consistent with
the other sources.

af7c03ea88 rpi: add support for Raspberry Pi Zero
For U-Boot's purposes, at present all we care about is ensuring there's

c4ea1edb70 rpi: fix revision scheme parsing
The RPi has two different schemes for encoding board revision values.
When adding RPi 2 support, I thought that the conflicting type field
values were to be interpreted based on bcm2835-vs-bcm2836. In fact, the
scheme bit determines the encoding. The RPi Zero uses the bcm2835 yet
uses the new encoding scheme. Fix the code to cater for this correctly.

dbe6f1eb93 rpi: get rid of BCM2835_BOARD_REV_* macros
There are two numbering schemes for the RPi revision values; old and new
scheme. The values within each scheme overlap. Hence, it doesn't make
sense to have absolute/global names for the revision IDs. Get rid of the
names and just use the raw revision/type values to set up the array of
per-revision data.

This change makes most sense when coupled with the next change. However,
it's split out so that the mechanical cut/paste is separate from the
logic changes for easier review and problem bisection.

Add CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG support and enable it to set
'board_rev' and 'board_name' envs.
'board_rev' can be used in scripts to determine what board we are running on
and 'board_name' for pretty printing.

79ad5cef15 ARM: rpi: add another revision of Raspberry Pi A+
Seen this one in the wild. Is labelled "Raspberry Pi Model A+ V1.1,
(C) Raspberry Pi 2014". A standard A+ board, much like the one with
version 0x12, didn't notice any differencies.

95b4f112f5 ARM: rpi: fix RPi1 board rev detection for warranty bit
Apparently the firmware's board rev response includes both the board
revision and some other data even on the RPi1. In particular, the
"warranty bit" is bit 24. We need to mask that out when looking up the
board ID.

914627fe1c ARM: rpi: consolidate board rev error checking
Create a fake model table entry with default values, so we can error
check the board rev value once when querying it from the firmware, rather
than error-checking for invalid board rev values every time the model
table is used.

3207d8fc9c ARM: rpi: only set usbethaddr on relevant systems
Model A and CM RPis don't have an on-board USB Ethernet device. Hence,
there's no point setting $usbethaddr based on the device fuses. Use the
model detection code to gate this. Note that the fuses are actually
programmed even on those devices though.
