arm: imx: Check header before calling spl_load_imx_container
Make sure we have an IMX header before calling spl_load_imx_container,
since if we don't it will fail with -ENOENT. This allows us to fall back to
legacy/raw images if they are also enabled.
This is a functional change, one which likely should have been in place
from the start, but a functional change nonetheless. Previously, all
non-IMX8 images (except FITs without FIT_FULL) would be optimized out if
the only image load method enabled supported IMX8 images. With this change,
support for other image types now has an effect.
There are seven boards with SPL_LOAD_IMX_CONTAINER enabled: three with
SPL_BOOTROM_SUPPORT:
imx93_11x11_evk_ld imx93_11x11_evk imx8ulp_evk
and four with SPL_MMC:
deneb imx8qxp_mek giedi imx8qm_mek
All of these boards also have SPL_RAW_IMAGE_SUPPORT and
SPL_LEGACY_IMAGE_FORMAT enabled as well. However, none have FIT support
enabled. Of the six load methods affected by this patch, only SPL_MMC and
SPL_BOOTROM_SUPPORT are enabled with SPL_LOAD_IMX_CONTAINER.
spl_romapi_load_image_seekable does not support legacy or raw images, so
there is no growth. However, mmc_load_image_raw_sector does support loading
legacy/raw images. Since these images could not have been booted before, I
have disabled support for legacy/raw images on these four boards. This
reduces bloat from around 800 bytes to around 200.
There are no in-tree boards with SPL_LOAD_IMX_CONTAINER and AHAB_BOOT both
enabled, so we do not need to worry about potentially falling back to
legacy images in a secure boot scenario.
Future work could include merging imx_container.h with imx8image.h, since
they appear to define mostly the same structures.

for switching to i2c-gpio was due to an issue we were seeing in the
Linux kernel where the CPU would lock up on certain adverse I2C bus
conditions. We were never able to reproduce the lockup in U-Boot but
assumed that was probably just luck.
Since then we have discovered that the lock up was due to the I2C
transaction offload engine in the I2C controller not coping with the
adverse bus conditions (basically it thinks there's another master and
waits for a STOP condition that never comes). U-Boot doesn't use the I2C
offload feature so is not susceptible to the lockup.

usb: ehci: mxs: Use regulator_set_enable_if_allowed()
Since commit 4fcba5d556b4 ("regulator: implement basic reference
counter") the return value of regulator_set_enable() may be EALREADY or
EBUSY for fixed/GPIO regulators.
Switch to using the more relaxed regulator_set_enable_if_allowed() to
continue if regulator already was enabled or disabled.
This fixes the following error when running the 'ums' command:
Extend the padding process of u-boot-nand.imx target by adding 10k bytes
of zeros to the end of the binary using the 'dd' command.
The existing padding method did not generate a functional binary,
as discussed in more detail in this thread [1]. Instead, we adopt the
end-padding calculation method documented in 'board/doc/colibri_imx7.rst'
as a reference, which is relevant for iMX7 with NAND storage.
Adding 10k bytes of zeros provides an approximate value that makes the
proper padding for these NAND devices.

toradex: colibri_imx7: Enable nand/emmc detection and set boot variant
Add detection of eMMC vs NAND devices on the Colibri iMX7
board. A GPIO is configured to detect the presence of an on-board resistor
that is configured differently based on the flash memory used. Depending on
the detection result, the 'variant' environment variable is set to '-emmc'
or cleared, indicating the type of storage device.
This enhancement improves variant detection during system initialization
through USB recovery mode, where U-Boot is loaded directly to RAM. This
allows variant detection for an accurate device tree selection.
board: toradex: verdin-imx8mm: set fixed LPDDR4 refresh rate as per errata ERR050805
Update lpddr4 configuration and training using updated spreadsheet and
tools from NXP using data from previous spreadsheet and verified
toward datasheet:
The most relevant update is related to errata ERR050805:
"DRAM: Controller automatic derating logic may not work when
the LPDDR4 memory temperature is above 85 °C at initialization"
Other relevant fixes:
- DRAMTMG7 register: corrected calculation of T_CKPDX parameter
(equal to tCKCKEH for LPDDR4)
- RANKCTL register: corrected calculations for ODTLon and ODTLoff
to follow the JEDEC specification
- ADDRMAP7 register: added support for 17-row devices
As per errata ERR050805:
An issue exists with the automatic derating logic of the DDR
controller that only samples the LPDDR4 MR4 register when the
Temperature Update Flag (TUF) field (MR4[7] ) is 1’b1. If the
LPDDR4 memory is initialized and starts operation above 85 °C
(MR4[2:0] > 3’b011), the MR4 Temperature Update Flag (TUF) will
not be set. The DDR Controller will therefore not automatically
adjust the memory refresh rate or de-rate memory timings based
on the LPDDR4 memory temperature. This may cause the controller
incorrectly setting the refresh period, potentially cause the
LPDDR4 memory losing data contents and lead to possible data
integrity issues above 85 °C.
Errata provides three possible workaround options, while option 2
is the most reasonable:
Disable the automatic derating logic of the DDR controller and
apply fixed x2 refresh rate (0.5x refresh). This option is
suitable for designs that are expected to boot at or above 85 °C
and memory’s MR4[2:0] (Refresh Rate) DOES NOT report the following
conditions:
3b101: 0.25x refresh, no de-rating
3b110: 0.25x refresh, with de-rating
3b111: SDRAM High temperature operating limit exceeded
mx8m: csf.sh: pad csf blob for u-boot.itb to CSF_SIZE minus IVT header
When built with CONFIG_IMX_HAB, the full FIT image, including stuff
tacked on beyond the end of the fdt structure, is expected to be (fdt
size rounded up to 0x1000 boundary)+CONFIG_CSF_SIZE.
Now, when the FIT image is loaded from a storage device, it doesn't
really matter that the flash.bin that gets written to target isn't
quite that big - we will just load some garbage bytes that are never
read or used for anything. But when flash.bin is uploaded via uuu,
it's important that we actually serve at least as many bytes as the
target expects, or we will hang in rom_api_download_image().
Extend the logic in the csf.sh script so that the csf blob is padded
to CONFIG_CSF_SIZE minus the size of the IVT header.
imx: spl_imx_romapi: avoid tricky use of spl_load_simple_fit() to get full FIT size
Currently, spl_imx_romapi uses a somewhat tricky workaround for the
fact that a FIT image with external data doesn't directly allow one to
know the full size of the file: It does a dummy spl_load_simple_fit(),
having the ->read callback remember the largest offset requested, and
then does a last call to rom_api_download_image() to fetch the
remaining part of the full FIT image.
We can avoid that by just keeping track of how much we have downloaded
already, and if the ->read() requests something outside the current
valid buffer, fetch up to the end of the current request.
The current method also suffers from not working when CONFIG_IMX_HAB
is enabled: While in that case u-boot.itb is not built with external
data, so the fdt header does contain the full size of the dtb
structure. However, it does not account for the extra CONFIG_CSF_SIZE
added by board_spl_fit_size_align(). And also, the data it hands out
during the first dummy spl_load_simple_fit() is of course garbage, and
wouldn't pass the verification.
So we really need to call spl_load_simple_fit() only once, let that
figure out just how big the FIT image is (including whatever data, CSF
or "ordinary" external data, has been tacked on beyond the fdt
structure), and always provide valid data from the ->read callback.
This only affects the CONFIG_SPL_LOAD_FIT case - I don't have any
hardware or experience with the CONFIG_SPL_LOAD_IMX_CONTAINER case, so
I leave that alone for now.
The hab signing script doc/imx/habv4/csf_examples/mx8m/csf.sh does
fdtget -t x u-boot.dtb /binman/imx-boot/uboot offset
to figure out the offset of u-boot.itb inside flash.bin. That works
fine for imx8mm, imx8mn, imx8mq, but fails for imx8mp because in that
case 'uboot' is merely a label and not actually the node name.
Homogenize these cases and make imx8mp the same as the other imx8m*
variants. The binman type is explicitly given and no longer derived
from the node name, and the csf.sh script will work for all four SOCs.
