Texas Instruments AM3358 based low-cost board using Octavo Systems OSD3358 SIP
with built-in TPS65217 PMIC and 512MB DDR3. Board features small 35mm x
55mm size, high-speed USB OTG, microSD and 72 0.1" expansion header
pins with 2xSPI, 2xI2C, 2xUART, USB, 8xADC, up-to-44 GPIO, PRU pins and much more.

This was tested using the am335x_evm_usbspl_defconfig.
Note that MII pins are enabled despite not having Ethernet on this
board. This avoids an issue where otherwise many timeout errors would be
generated. See https://e2e.ti.com/support/arm/sitara_arm/f/791/t/298976

serial# variable is needed to show the device correctly in "fastboot
devices" output. It's useful when we have several devices (in fastboot
mode) connected to single host and want to choose which one to flash.
We can't use omap_die_id_serial() for this, because AM335x lacks
DIE_ID, as can be seen from AM335x TRM. Let's do next:
- reuse board_serial variable (obtained from EEPROM in
set_board_info_env() function) to set serial#
- if board_serial is "unknown", reuse ethaddr variable to set serial#

commit 0650798824 ("board: am335x: Introduce scale_vcores")
updated voltages of each board based on efuse. It updated
beagle bone specific voltages under the condition board_is_bone().
But this is true only for BeagleBoneWhite. Due to which voltages
are not configured for BBB, BBW as wrong device is being probed.
So create a common function board_is_beaglebonex() which includes
am335x based beagle family. Use this for updating voltages.
Also remove extra if condition for selecting voltages which is
done later using a switch case and match usb current limit as

function for all platforms.
Details:
- Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for
OMAP4/5), so we can obtain status register in common way
- For now ctrl structure for AM33xx/OMAP3 contains only status register
address
- Run hw_data_init() in order to assign ctrl to proper structure
- Remove DEVICE_MASK and DEVICE_GP definitions as they are not used
(DEVICE_TYPE_MASK and GP_DEVICE are used instead)
- Guard structs in omap_common.h with #ifdefs, because otherwise
including omap_common.h on non-omap4/5 board files breaks compilation

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.

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.
