When the device port is in a low power state [U3/L2/Not Connected],
accesses to usb device registers may take a long time. This could lead to
potential core hang when the controller registers are accessed after the
port is disabled by setting DEVDS field. Setting the fast register access
bit ensures that the PHY clock is keeping up in active state.
Therefore, set fast access bit to ensure the accesses to device registers
are quick even in low power states.

This is not really a new board but rather a minimal bootloader solution
for the AM437x GP EVM. In terms of interfaces, it only supports booting
from MMC0 or UART0 and only activates a minimal set of drivers that are
that are necessary to run the device such as DDR, I2C, and PMIC.
The goal is to provide a bare minimum starting point to boot Linux for
basing custom board-ports on. The limited complexity of this solution
should make it easier to achieve a successful boot to U-Boot prompt vs.
trying to pair down the full-featured multi-platform AM437x U-Boot
available through am43xx_evm_defconfig.
