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.

Updates configs/am43xx_evm.h to use CONFIG options from
SOC specific Kconfig file for various calculations.
On AM43x devices, the address of SPL entry point depends on
the device type, i.e. whether it is secure or non-secure.
Further, for non-secure devices, the SPL entry point is different
between USB HOST boot mode, other "memory" boot modes (MMC, NAND)
and "peripheral" boot modes (UART, USB)
To add to the complexity, on secure devices, in addition to the
above differences, the SPL entry point can change because of the
space occupied by other components (other than u-boot or spl)
that go into a secure boot image.
To prevent the user from having to modify source files every time
any component of the secure image changes, the value of
CONFIG_SPL_TEXT_BASE has been set using a Kconfig option that
is supplied in the am43xx_*_defconfig files
Using the CONFIG options also enables us to do away with some
compile time flags that were used to specify CONFIG_SPL_TEXT_BASE
for different boot modes.
On QSPI devices, the same problem described above occurs w.r.t. the
address of the u-boot entry point in flash, when booting secure
devices. To handle this, CONFIG_SYS_TEXT_BASE is also setup via
a Kconfig option and the defconfig files.
