Initialize EMIF OCP_CONFIG registers REG_COS_COUNT_1, REG_COS_COUNT_2,
and REG_PR_OLD_COUNT field for Beaglebone-Black and am335x-evm. With
the default values LCDC suffers from DMA FIFO underflows and frame
synchronization lost errors. The initialization values are the highest
that work flawlessly when heavy memory load is generated by CPU. 32bpp
colors were used in the test. On BBB the video mode used 110MHz pixel
clock. The mode supported by the panel of am335x-evm uses 30MHz pixel
clock.

e607ec993b board: am335x-icev2: add ethernet phy mode detection logic
Both ethernet ports can be used as CPSW ethernet (RMII mode)
or PRU ethernet (MII mode) by setting the jumper near the port.
Read the jumper value and set the pinmux, external mux and
PHY clock accordingly.

As jumper line is overridden by PHY RX_DV pin immediately
after bootstrap (power-up/reset), we have to use GPIO edge
detection to capture the jumper line status.

As u-boot doesn't provide any infrastructure for GPIO edge
detection, we directly access the GPIO registers.

97f3a178b2 board: AM335x-ICEv2: Add cpsw support
In order to enable cpsw on AM335x ICEv2 board, the following needs to be done:

1)There are few on board jumper settings which gives a choice between
cpsw and PRUSS, that needs to be properly selected[1]. Even after selecting
this, there are few GPIOs which control these muxes that needs to be held high.

2) The clock to PHY is provided by a PLL-based clock synthesizer[2] connected
via I2C. This needs to properly programmed and locked for PHY operation.
And PHY needs to be reset before before being used, which is also held by
a GPIO.

3) RMII mode needs to be selected.

been declaring some fields as 0 when they will be initialized that way.

GPMC controller is common IP to interface with both NAND and NOR flash devices.
Also, it supports max 8 chip-selects, which can be independently connected to
any of the devices.
But ROM code expects the boot-device to be connected to only chip-select[0].
Thus to resolve conflict between NOR and NAND boot. This patch:
- combines NOR and NAND configs spread in board files to common gpmc_init()
- configures GPMC based on boot-mode selected for SPL boot.

Add a am33xx_spl_board_init (and enable the PMICs) that we may see,
depending on the board we are running on.  In all cases, we see if we
can rely on the efuse_sma register to tell us the maximum speed.  In the
case of Beaglebone White, we need to make sure we are on AC power, and
are on later than rev A1, and then we can ramp up to the PG1.0 maximum
of 720Mhz.  In the case of Beaglebone Black, we are either on PG2.0 that
supports 1GHz or PG2.1.  As PG2.0 may or may not have efuse_sma set, we
cannot rely on this probe.  In the case of the GP EVM, EVM SK and IDK we
need to rely on the efuse_sma if we are on PG2.1, and the defaults for
PG1.0/2.0.

94d77fb656 ARM: AM33xx: Cleanup dplls data
Locking sequence for all the dplls is same.
In the current code same sequence is done repeatedly
for each dpll. Instead have a generic function
for locking dplls and pass dpll data to that function.

This is derived from OMAP4 boards.

c5c7a7c32d am335x_evm: Add support to boot from NOR.
NOR requires that s_init be within the first 4KiB of the image so that
we can perform the rest of the required pinmuxing to talk with the rest
of NOR that we are found on.  When NOR_BOOT is set we save our
environment in NOR at 512KiB and a redundant copy at 768KiB.  We avoid
using SPL for this case and u-boot.bin is written directly to the start
of NOR.

We enclose the DMM-related parts of arch/arm/cpu/armv7/am33xx/emif4.c
with TI81xx checks as at this time U-Boot does not discard unused
sections in the main build and this code relies on functions specific to
(and only provided in) ti81xx-related code.

cd8845d7a4 am335x_evm: Add support for the NOR module on the memory cape
This patch adds support for the NOR module that attaches
to the memory cape for a Beaglebone board. This does not
add booting support; only support so that you can boot from
SD/MMC and see the NOR module so that it can be programmed.

ace4275eb3 am335x_evm: Rework board_is_foo() checks
We rework the various board_is_foo() checks to take a pointer to
struct am335x_baseboard_id rather than using a local copy in board.c.
This allows us to make use of the same checks in mux.c as well as fixing
problems when this code could be running from read-only memory.
