2df59b2bd4 Remove duplication of table_compute_checksum function
It seems like there was some merge error when first cleaning up and
sharing this function.  We have both an inline version of the function
in include/tables_csum.h and a non-inline version in lib/tables_csum.c.
Rework things so that we only have the non-inline version (due to number
of calls, we should not inline this).

34855b39be serial: smh: Implement puts for DM
This adds an implementation of puts for DM. The implementation is not as
clean as for the non-DM puts because we have to handle non-nul-terminated
string. We also handle short writes (though these are probably very
unusual).

679190c41a test: serial: Add test for putc/puts
This adds a test to ensure that puts is equivalent to putc called in a
loop. We don't verify the contents of the message to avoid having to
record console output a second time (though that could be added in the
future). The globals are initialized to non-zero values to avoid a
warning; in particular, the character count is off-by-one (but we always
make relative measurements).

2c777488b6 serial: Fix _serial_puts using \n\r instead of \r\n
A string like "test\n" would be broken up into the following sequence of
prints by _serial_puts:

	puts("test\n")
	putc('\r')

Although functionally this is the same as \r\n, it is not the standard
sequence and caused tests to fail. Fix this by excluding the '\n' from
the initial print. The above string will now be broken up like

	puts("test")
	puts("\r\n")

Since we may now need to call ops->puts twice (with the associated retry
logic), break that part of the function off into a helper.

af298f3dcd cmd: ubi.c: skip part command if right partition is already attached
Attaching a UBI partition may take a while, since scanning the memory is
required.
It thus makes sense to avoid a detach/scan/attach cycle when the right
partition is already attached, and let the calling process call 'detach'
beforehand if it needs it.

This commit checks for the currently attached UBI partition, and skips
reattaching if not needed, showing an information.

cb61b2fb2b ARM: imx: Get rid of only i.MX8M SMCCC arch call
This is the only place where i.MX8M code does SMCCC call, remove it.
The output has little value as it prints some part of commit ID, and
worse, if there is no SMC handler installed, the code outright hangs
or crashes the system.

By removing this one instance of SMCCC call, U-Boot no longer depends
on SMC handlers and can boot without hanging in any case. If there is
a need to dump this commit ID, use CMD_SMC instead and do 'smc' call
from U-Boot shell or scripts instead of hard-coding SMCCC dependency
into architecture code. This particular code can be replaced by:
 => smc 0xc2000003 0 0 0 0 0 0

The CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR is really overloaded in

fd44d48f24 imx8mm-cl-iot-gate: Add redundand environment support
Add redundand environment support as it is required
by SWUpdate.

While at it, also adjust the CONFIG_ENV_OFFSET to a more appropriate
larger offset as done on other i.MX8M defconfigs.

ea10bea68d imx8mm-cl-iot-gate: Retrieve the serial number from EEPROM
The serial number is located at offset 0x14 of the EEPROM
under i2c0 bus at address 0x54.

To print the serial number in Linux:

SERNUM=$(cat /proc/device-tree/serial-number)
echo $SERNUM

6924bc7ca2 imx8mm-cl-iot-gate: Retrieve the DDR type from EEPROM
Currently, the DDR type is retrieved by iteracting inside an array
of possible DDR types.

This may take saveral attempts, which slows the overall U-Boot process
and does not provide a good user experience:
