7adafc146f imx: fix CAAM base for i.MX6UL
HW accelerated "hash sha256 ..." command doesn't work on i.MX6UL, we get
"CAAM was not setup properly or it is faulty" error message.

This is due to wrong CAAM base 0x02100000, on i.MX6UL the CAAM base
address is 0x02140000. Fix it.

Note: with this patch applied the "hash sha256" commant still has some
issues on i.MX6UL ("Invalid KEY Command" or other errors). With data
cache off the "hash sha256" command works as expected.

314d9f7e3e imx: syscounter: make sure asm is volatile
Without the volatile attribute, compilers are entitled to optimize out
the same asm().  In the case of __udelay() in syscounter.c, it calls
`get_ticks()` twice, one for the starting time and the second in the
loop to check the current time.  When compilers inline `get_ticks()`
they see the same `mrrc` instructions and optimize out the second one.
This leads to infinite loop since we don't get updated value from the
system counter.

Here is a portion of the disassembly of __udelay:

  88:	428b      	cmp	r3, r1
  8a:	f8ce 20a4 	str.w	r2, [lr, #164]	; 0xa4
  8e:	bf08      	it	eq
  90:	4282      	cmpeq	r2, r0
  92:	f8ce 30a0 	str.w	r3, [lr, #160]	; 0xa0
  96:	d3f7      	bcc.n	88 <__udelay+0x88>
  98:	e8bd 8cf0 	ldmia.w	sp!, {r4, r5, r6, r7, sl, fp, pc}

Note that final jump / loop at 96 to 88, we don't have any `mrrc`.

With a volatile attribute, the above changes to this:

  8a:	ec53 2f0e 	mrrc	15, 0, r2, r3, cr14
  8e:	42ab      	cmp	r3, r5
  90:	f8c1 20a4 	str.w	r2, [r1, #164]	; 0xa4
  94:	bf08      	it	eq
  96:	42a2      	cmpeq	r2, r4
  98:	f8c1 30a0 	str.w	r3, [r1, #160]	; 0xa0
  9c:	d3f5      	bcc.n	8a <__udelay+0x8a>
  9e:	e8bd 8cf0 	ldmia.w	sp!, {r4, r5, r6, r7, sl, fp, pc}
  a2:	bf00      	nop

I'm advised[1] to put volatile on all asm(), so this commit also adds it
to the asm() in timer_init().

b5b0e4e351 imximage: Remove failure when no IVT offset is found

  CFGS    board/freescale/vf610twr/imximage.cfg.cfgtmp
  MKIMAGE u-boot-dtb.imx
Error: No BOOT_FROM tag in board/freescale/vf610twr/imximage.cfg.cfgtmp
arch/arm/mach-imx/Makefile💯 recipe for target 'u-boot-dtb.imx' failed

Later on, when running mkimage for the u-boot.imx it will succeed in
finding the IVT offset.

Looks like some race condition happening during parallel build when
processing mkimage for u-boot-dtb.imx and u-boot.imx.

A proper fix still needs to be implemented, but as a workaround let's
remove the error when the IVT offset is not found.

It is useful to have such message, especially during bring-up phase,
but the build error that it causes is severe, so better avoid the
build error for now.

The error checking can be re-implemented later when we have a proper
fix.

1e5f89881a gpio: pca953x_gpio: Support label setting from DT
The PCA953x driver uses "gpio@%x_" as the GPIO bank name, where "%x" is
instantiated with the I2C address of the chip. While this works, it
becomes very confusing if a board has multiple PCAs with the same
address on different I2C busses, and it also becomes an issue when a
GPIO's value is to be set via the 'gpio' command, because this command
only ever sets the value of the first device it encounters, leaving the
other devices inaccessible to the command.

As to not break boards that rely on this naming scheme, we introduce a
new device tree string property "label" for the driver. If it exists, it
is used to build a bank name of the form "%s@%x_" (where %x is still
instantiated with the I2C address). If it does not exist, the legacy
labeling scheme is used.

cd655514aa tools/env: allow equal sign as key value separation
Treat the first equal sign as a key/value separation too. This makes
the script files compatible with mkenvimage input file format. It
won't support variables with equal signs anymore, but this seems not
really like a loss.

afe0e6bddf Infineon TPM: Fix potential buffer overruns
Ensure that the Infineon I2C and SPI TPM driver performs adequate
validation of the length extracted from the TPM response header.
This patch prevents integer underflow when the length was too small,
which could lead to memory corruption.
