f3543e6944 treewide: Drop image_header_t typedef
This is not needed and we should avoid typedefs. Use the struct instead
and rename it to indicate that it really is a legacy struct.

cd2f9031e4 spl: spl_spi: add spi_nor_remove() to soft reset flash
On probe, the SPI NOR core will put a flash in 8D mode if it
supports it. But Linux as of now expects to get the flash in
1S mode. Handing the flash to Linux in Octal DTR mode means
the kernel will fail to detect the flash.

This commit adds an option to soft reset the flash after
spl_spi_load_image() so that the flash can be reset to 1S mode
and subsequent spi-nor probe in Linux does not fail, since
spl_spi_load_image() performs spi_flash_probe() the remove is
added after completion loading images in spi_flash_probe() itself.

Tested on J721E EVM with 5.10 Linux kernel.

Linux spi-nor probe without the fix:
root@j7-evm:~# dmesg | grep spi-nor
[    4.928023] spi-nor spi0.0: unrecognized JEDEC id bytes: ff ff ff ff ff ff
[    4.934938] spi-nor: probe of spi0.0 failed with error -2

Linux spi-nor probe with the fix:
root@j7-evm:~# dmesg | grep spi-nor
[    4.904484] spi-nor spi0.0: mt35xu512aba (65536 Kbytes)

6dd18a6568 common: spl: spl_spi: add support for dynamic override of sf bus
Currently the SPI flash to load from is defined through the compile
time config CONFIG_SF_DEFAULT_BUS and CONFIG_SF_DEFAULT_CS, this
prevents the loading of binaries from different SPI flash using the
same build.E.g. supporting QSPI flash boot and OSPI flash boot
on J721E platform is not possible due to this limitation.

This commit adds lookup functions spl_spi_boot_bus()
and spl_spi_boot_cs for identifying the flash device based on the
selected boot device, when not overridden the lookup functions are
weakly defined in common/spl/spl_spi.c.

7115007ccf spl: Make use of CONFIG_IS_ENABLED(OS_BOOT) in SPL/TPL common code paths
When building a system that has both TPL and SPL_OS_BOOT, code which
tests for CONFIG_SPL_OS_BOOT will be built and enabled in TPL, which is
not correct.  While there is no CONFIG_TPL_OS_BOOT symbol at this time
(and likely will not ever be) we can use CONFIG_IS_ENABLED(OS_BOOT) in
these common paths to ensure we only compile these parts in the SPL
case.

5fce287556 SPL: Add support for specifying offset between header and image
Some image types (e.g. kwbimage v1) store the offset to SPL binary and
offset to U-Boot proper binary in their headers. To avoid reading SPL
binary when loading U-Boot proper, add support for specifying offset in
struct spl_image_info, which defines the offset from the beginning of
the header and the beginning of the executable data.

Initial support is added only for SPI, MMC and SATA code. We can extend
it later if needed.

b0cc1b846f dm: spi: Read default speed and mode values from DT
This patch update the behavior introduced by
commit 96907c0fe5 ("dm: spi: Read default speed and mode values from DT")

In case of DT boot, don't read default speed and mode for SPI from
CONFIG_* but instead read from DT node. This will make sure that boards
with multiple SPI/QSPI controllers can be probed at different
bus frequencies and SPI modes.

Remove also use in boards of the value speed=0 (no more supported)
for ENV in SPI by using CONFIG_ENV_SPI_MAX_HZ=0.

DT values will be always used when available (full DM support of
SPI slave with available DT node) even if speed and mode are requested;
for example in splash screen support (in splash_sf_read_raw)
or in SPL boot (in spl_spi_load_image).
The caller of spi_get_bus_and_cs() no more need to force speed=0.

But the current behavior don't change if the SPI slave is not
present (device with generic driver is created automatically)
or if platdata is used (CONFIG_OF_PLATDATA).

04ce5427bd spl: Weed out CONFIG_SYS_TEXT_BASE usage
The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location
is available and can be corrupted by loading ie. uImage or fitImage
headers there. Sometimes it could be beneficial to load the headers
elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we
still want to parse the image headers in some local onchip memory to
ie. extract firmware from that image.

Add the possibility to override the location where the headers get
loaded by introducing new function, spl_get_load_buffer() which takes
two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the
data that are to be loaded there -- and returns a valid buffer address
or hangs the system. The default behavior is the same as before, add
the offset to CONFIG_SYS_TEXT_BASE and return that address. User can
override the weak spl_get_load_buffer() function though.

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.

2bac55bc16 spl: spi: override CONFIG_SYS_SPI_U_BOOT_OFFS via /config-property
For the RK3399-Q7, we need some flexibility (depending on the feature
set we include in the SPL stage and how large our SPI flash is) in
positioning the SPL payload (i.e. the FIT image containing U-Boot, ATF
and the M0 payload) in our SPI flash.

To avoid having to deal with this through different U-Boot images, we
introduce a the '/config/u-boot,spl-payload-offset' property node
allow it to override the default setting.
