env/sf.c: honour CONFIG_SPL_SAVEENV
Deciding whether to compile the env_sf_save() function based solely on
CONFIG_SPL_BUILD is wrong: For U-Boot proper, it leads to a build
warning in case CONFIG_CMD_SAVEENV=n (because the initialization of
the .save member is guarded by CONFIG_CMD_SAVEENV, while the
env_sf_save() function is built if !CONFIG_SPL_BUILD - and even
without the CONFIG_CMD_SAVEENV guard, the env_save_ptr() macro would
just expand to NULL, with no reference to env_sf_save visible to the
compiler). And for SPL, when one selects CONFIG_SPL_SAVEENV, one
obviously expects to actually be able to save the environment.
The compiler warning can be fixed by using a "<something> ?
env_sf_save : NULL" construction instead of a macro that just eats its
argument and expands to NULL. That way, if <something> is false,
env_sf_save gets eliminated as dead code, but the compiler still sees
the reference to it.
For <something>, we can use CONFIG_IS_ENABLED(SAVEENV), which is true
precisely:
- For U-Boot proper, when CONFIG_CMD_SAVEENV is set (because
CONFIG_SAVEENV is a hidden config symbol that gets set if and only
if CONFIG_CMD_SAVEENV is set).
- For SPL, when CONFIG_SPL_SAVEENV is set.
As a bonus, this also removes quite a few preprocessor conditionals.
This has been run-time tested on a mpc8309-derived board to verify
that saving the environment does indeed work in SPL with these patches
applied.

There is no real need to exactly define space for saving patterns for
alternate memory test. It is much easier to allocate space on the stack and
use it instead of trying to find out space where pattern should be saved.
For example if you want to test the whole DDR memory you can't save patter
to DDR and you need to find it out. On Xilinx devices DDR or OCM addresses
were chosen but that means that OCM needs to be mapped and U-Boot has
access permission there.
It is easier to remove this limitation and simply save it on stack because
it is very clear that memory test can't rewrite U-Boot and U-Boot has also
full access to memory where runs from.

To fill the exponent field of the rsa_public_key struct, rsa_mod_exp_sw

This came to light when in my spl-fit-signature the key-name exceeded

key_prop.public_exponent itself is actually a void-pointer, fdt_getprop()

exponent is represented as 2 32bit numbers, so assuming a 64bit alignment

uart: pl011: Add proper DM clock support
Even though the PL011 UART driver claims to be DM compliant, it does not
really a good job with parsing DT nodes. U-Boot seems to adhere to a

the node, or to have an extra "clock" property holding the base
*frequency* value for the baud rate generator.
DTs in the U-Boot tree seem to have been hacked to match this
requirement.
The official binding does not mention any of these properties, instead
recommends a standard "clocks" property to point to the baud base clock.
Some boards use simple "fixed-clock" providers, which U-Boot readily
supports, so let's add some simple DM clock code to the PL011 driver to
learn the rate of the first clock, as described by the official binding.
These clock nodes seem to be not ready very early in the boot process,
so provide a fallback value, by re-using the already existing

arm: juno: Fix Juno address variables
The U-Boot documentation explains that variables ending with "_r" hold

The default variables for the Juno board pointing to the kernel and DTB
load addresses were not complying with this scheme: they lack the
extension, but point to DRAM. This is particularly confusing since the
Juno board features parallel NOR flash, so there *is* a memory mapped
NOR address holding a DTB, for instance.
Fix the variables to use the proper names, changing initrd_addr to
ramdisk_addr_r on the way, which seems to be more prevelant and
documented. On the way adjust the FDT load address to be situated
*before* the kernel, since users happened to overwrite the DTB by the
kernel clearing its .BSS section during initialisation.
Also remove the fdt_high and initrd_high variables (which were set
to -1), to allow U-Boot moving those images around.
This should avoid many problems in the future, but breaks loading
Linux kernels < v4.2, since they expect the DTB to be loaded in the same
512MB region as the kernel. If you need to load such an old kernel,
please set fdt_high to either 0xffffffffffffffff or 0xa0000000 (if you
load the kernel to the beginning of DRAM).
That fixes loading debug kernels, which happened to overwrite the DTB on

cmd: Add an indication of 32/64-bit to bdinfo
It is useful to know what mode U-Boot is running in. Add a message at the
end of the 'bdinfo' output.

x86: Move work-around out of cpu_jump_to_64bit_uboot()
At present this function copies U-Boot from the last 1MB of ROM. This is
not the right way to do it. Instead, the binman symbol should provide the
location.
But in any case the code should live in the caller,
spl_board_load_image(), so that the 64-bit jump function can be used
elsewhere. Move it.

x86: Allow building an SPL image for coreboot
Coreboot runs in 32-bit mode and cannot run a 64-bit U-Boot. To get around
this we can build a combined image with 32-bit SPL and 64-bit U-Boot. Add
a build rule and binman definition for this.

In two files README.qe_firmware is referenced which never made it into the
U-Boot tree. The README is available in the Linux kernel tree.
Update the references.
