The patch implements secure booting for the mvebu architecture.
This includes:
- The addition of secure headers and all needed signatures and keys in
mkimage
- Commands capable of writing the board's efuses to both write the
needed cryptographic data and enable the secure booting mechanism
- The creation of convenience text files containing the necessary
commands to write the efuses
The KAK and CSK keys are expected to reside in the files kwb_kak.key and
kwb_csk.key (OpenSSL 2048 bit private keys) in the top-level directory.

The function image_create_config_parse_oneline is pretty complex, and
since more parameters will be added to support secure booting, we
refactor the function to make it more readable.
Also, when a line contained just a keyword without any parameters,
strtok_r returned NULL, which was then indiscriminately fed into atoi,
causing a segfault. To correct this, we add a NULL check before feeding
the extracted token to atoi, and print an error message in case the
token is NULL.

To enable secure boot, we need to jump back into the BootROM to continue
the SoC's boot process instead of letting the SPL load and run the main
U-Boot image.
But, since the u-boot-spl.img (including the 64 byte header) is loaded
by the SoC as the main image, we need to compensate for the header
length to get a correct entry point.
Thus, we subtract the header size from the destination address, so that
the execution address points at the actual entry point of the image.
The current boards ignore both parameters anyway, so this change shouldn't
concern them.

Currently, SPL (u-boot-spl.bin) and U-Boot (u-boot.bin) are stored

The Boot ROM supports authentication feature to prevent malformed
software from being run on products. The signature is added at the
tail of the second stage loader (= SPL in U-boot terminology).
The size of the second stage loader was 64KB, and it was consistent
across SoCs. The situation changed when LD20 SoC appeared; it loads
80KB second stage loader, and it is the only exception.
Currently, CONFIG_SPL_PAD_TO is set to 64KB and U-Boot proper is
loaded from the 64KB offset of non-volatile devices. This means the
signature of LD20 SoC (located at 80KB offset) corrupts the U-Boot
proper image.
Let's move the U-Boot proper image to 128KB offset. It uses 48KB
for nothing but padding, and we could actually locate the U-Boot
proper at 80KB offset. However, the power of 2 generally seems a
better choice for the offset address.

For LD20 SoC, the last 64 byte of each DRAM bank is used for the

U-Boot needs to set up available memory area(s) in dram_init() and
dram_init_banksize(). It is platform-dependent how to detect the
memory banks. Currently, UniPhier adopts the memory banks _alleged_
by DT. This is based on the assumption that users bind a correct DT
in their build process.
Come to think of it, the DRAM controller has already been set up
before U-Boot is entered (because U-Boot runs on DRAM). So, the
DRAM controller setup register seems a more reliable source of any
information about DRAM stuff. The DRAM banks are initialized by
preliminary firmware (SPL, ARM Trusted Firmware BL2, or whatever),
so this means the source of the reliability is shifted from Device
Tree to such early-stage firmware. However, if the DRAM controller
is wrongly configured, the system will crash. If your system is
running, the DRAM setup register is very likely to provide the
correct DRAM mapping.
Decode the SG_MEMCONF register to get the available DRAM banks.
The dram_init() and dram_init_banksize() need similar decoding.
It would be nice if dram_init_banksize() could reuse the outcome
of dram_init(), but global variables are unavailable at this stage
because the .bss section is available only after the relocation.
As a result, SG_MEMCONF must be checked twice, but a new helper
uniphier_memconf_decode() will help to avoid code duplication.

The two arrays ddrphy_{op,ip}_dq_shift_val, occupy more than 3.8 KB
memory footprint, which is significant in SPL.
There are PHY parameters for 5 boards, but they are actually not
board specific, but SoC specific. After all, we just need to have
2 patterns, for LD20 and LD21. Also, the shift values are small
enough to become "short" type instead of "int". This change will
save about 3 KB memory footprint.
