83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

eff0c977b3 Add support for BeagleBoard.org PocketBeagle
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
for some related discussion.

6f6b7cfa89 Convert all of CONFIG_CONS_INDEX to Kconfig
This converts the following to Kconfig:
   CONFIG_CONS_INDEX

We have existing entries for this option in a number of places, with
different guards on them.  They're also sometimes used for things not
directly inside of the serial driver.  First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it.  Next, consolidate all of these into the single entry in
drivers/serial/Kconfig.  Finally, introduce CONS_INDEX_[023456] so that
we can imply a correct value here to make the defconfig side of this
smaller.

fc228dc96c board: am335x: Set serial# variable
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#

9f7923c73c board: ti: am335x: Fix scale_vcore for beaglebones
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
before the commit 0650798824.

00bbe96eba arm: omap: Unify get_device_type() function
Refactor OMAP3/4/5 code so that we have only one get_device_type()
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

Buildman script was run for all OMAP boards. Result output:
    arm: (for 38/616 boards)
        all +352.5
        bss -1.4

c19a28bc65 board: am335x/mux: Do not hang when encountering a bad EEPROM
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.

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.

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.

505ea6e82a board: am33xx: fit: add support for selecting dtb dynamically
FIT allows for a multiple dtb in a single image. SPL needs a way to
detect the right dtb to be used. Adding support for the same.

50149ea37a efi_loader: Add runtime services
After booting has finished, EFI allows firmware to still interact with the OS
using the "runtime services". These callbacks live in a separate address space,
since they are available long after U-Boot has been overwritten by the OS.

This patch adds enough framework for arbitrary code inside of U-Boot to become
a runtime service with the right section attributes set. For now, we don't make
use of it yet though.

We could maybe in the future map U-boot environment variables to EFI variables
here.

the HDMI port and addition of two Grove connectors (i2c2 and usart2).

This board can be identified by the 1A value after A335BNLT (BBB) in the at24 eeprom:
1A: [aa 55 33 ee 41 33 33 35  42 4e 4c 54 1a 00 00 00 |.U3.A335BNLT....|]

9f13b6d147 ARM: AM335x: mux: change mmc0 cd pinmux from mmc0_sdcd to gpio
Currently omap_hsmmc driver doesn't use sdcd pin to detect
whether the card is present or not. Instead the same pin is used
as GPIO to detect card presence. So change the pin mux mode from
mmc0_sdcd to gpio0_6.
