In commit ad6054f1fe128f797b6eb2964afca6674b584785 where support for the
Sancloud BeagleBone Enhanced (BBE) was added, new conditional
configuration of either MII pin muxing or RGMII pin muxing is done
depending on the board type. However, the old call to set up MII pin
muxing was not removed.
This may result in misconfiguration of the pin muxing for the BBE or
duplicate configuration for other boards and so we remove this obsolete
call.

DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. The goal is to eventually remove DM_I2C_COMPAT
when all I2C "clients" have been migrated to use the DM API.
This a step in that direction for the TI based platforms.

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.
https://beagleboard.org/pocket
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

In most cases, the SPL and u-boot.img will be on the same boot media.
Since the SPL was loaded by the boot rom, the pinmux will already have
been configured for this media. This, the board will still be able to
boot successfully, or at least reach the u-boot console, where more
recovery options are available.
I've encountered this on a beaglebone black with a corrupted EEPROM.
Removing this check allowed the board to boot successfully. I've also
seen this on EVM-based boards with an unprogrammed EEPROM. On those
boards, for some reason there were no UART messages. This made it look
as if the SOC was dead.
Remove the hang(), as it is not a fatal error. Also reformat the error
message to be clearer as to the cause. The original message made it
appear as if the wrong binary was being loaded.

Currently omap_hsmmc driver doesn't use sdcd pin to detect

In the case of Beaglebone Black we only want to set the NAND or NOR cape
pinmux when the config has been specifically modified by the user for
this non-default case. Make the default be to set the MMC1 (eMMC)
pinmux. We don't need similar changes for Beaglebone White as there is
nothing on MMC1 by default there.

This patch adds support of NOR cape[1] for both Beaglebone (white) and
Beaglebone(Black) boards. NOR Flash on this cape is connected to GPMC
chip-select[0] and accesses as external memory-mapped device.
This cape has 128Mbits(16MBytes), x16, CFI compatible NOR Flash device.
As GPMC chip-select[0] can be shared by multiple capes so NOR profile is
not enabled by default in boards.cfg. Following changes are required to
enable NOR cape detection when building am335x_boneblack board profile.

Beaglebone Board can be connected to expansion boards to add devices to them.
These expansion boards are called 'capes'. This patch adds support for
following versions of Beaglebone(AM335x) NAND capes
(a) NAND Device with bus-width=16, block-size=128k, page-size=2k, oob-size=64
(b) NAND Device with bus-width=16, block-size=256k, page-size=4k, oob-size=224
Further information and datasheets can be found at [1] and [2]
* How to boot from NAND using Memory Expander + NAND Cape ? *
- Important: As BOOTSEL values are sampled only at POR, so after changing any
setting on SW2 (DIP switch), disconnect and reconnect all board power supply
(including mini-USB console port) to POR the beaglebone.
- Selection of ECC scheme
for NAND cape(a), ROM code expects BCH8_HW ecc-scheme
for NAND cape(b), ROM code expects BCH16_HW ecc-scheme
- Selction of boot modes can be controlled via DIP switch(SW2) present on
Memory Expander cape.
SW2[SWITCH_BOOT] == OFF follow default boot order MMC-> SPI -> UART -> USB
SW2[SWITCH_BOOT] == ON boot mode selected via DIP switch(SW2)
So to flash NAND, first boot via MMC or other sources and then switch to
SW2[SWITCH_BOOT]=ON to boot from NAND Cape.
- For NAND boot following switch settings need to be followed
SW2[ 1] = OFF (SYSBOOT[ 0]==1: NAND boot mode selected )
SW2[ 2] = OFF (SYSBOOT[ 1]==1: -- do -- )
SW2[ 3] = ON (SYSBOOT[ 2]==0: -- do -- )
SW2[ 4] = ON (SYSBOOT[ 3]==0: -- do -- )
SW2[ 5] = OFF (SYSBOOT[ 4]==1: -- do -- )
SW2[ 6] = OFF (SYSBOOT[ 8]==1: 0:x8 device, 1:x16 device )
SW2[ 7] = ON (SYSBOOT[ 9]==0: ECC done by ROM )
SW2[ 8] = ON (SYSBOOT[10]==0: Non Muxed device )
SW2[ 9] = ON (SYSBOOT[11]==0: -- do -- )

[2] http://beagleboardtoys.info/index.php?title=BeagleBone_4Gb_16-Bit_NAND_Module
*IMPORTANT NOTE*
As Beaglebone board shares the same config as AM335x EVM, so following
changes are required in addition to this patch for Beaglebone NAND cape.
(1) Enable NAND in am335x_beaglebone board profile
(2) Add CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config because:
- AM335x EVM has NAND device with datawidth=8, whereas
- Beaglebone NAND cape has NAND device with data-width=16

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.

This patch extends the am335x_evm board for the AM335x IDK.
The IDK board uses MII for the ethernet phy (same as
Beaglebone board) and MMC0 for storage (but without
card detect line).
The IDK uses UART3 for console. So u-boot must be build
with CONFIG_SERIAL4 and CONFIG_CONS_INDEX=4 or for
the am335x_evm_uart3 board configuration as introduced
by Andrew Bradfords recent patch series "am33xx: Enable
UART {1,2,3,4,5}...". When using the IDK with console on UART0,
those patches are not required. In this case the board
slightly needs to be modified.
