ARM: uniphier: make update commands more flexible for ATF

2017-01-29T11:59:08+00:00

Currently, SPL (u-boot-spl.bin) and U-Boot (u-boot.bin) are stored
in non-volatile devices, and some environments are defined to update
the images easily.

When ARM Trusted Firmware is fully used, SPL is not used.  U-Boot
proper is contained as BL33 into FIP (Firmware Image Package), which
is standard container used by ATF.  Allow to use it.

ARM: uniphier: change CONFIG_SPL_PAD_TO to 128KB

2017-01-29T11:59:08+00:00

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.

ARM: uniphier: change the offset to environment storage area

2017-01-29T11:59:08+00:00

When ARM Trusted Firmware is used, bl1.bin + fip.bin exceeds 512KB,
so the boot image and the current environment area will overlap.
Move the environment storage to 1MB offset.

ARM: uniphier: set initrd_high environment to skip initrd relocation

2017-01-29T11:59:08+00:00

The boot_ramdisk_high() checks the environment "initrd_high" and,
if it is set to (ulong)-1, skip the initrd relocation.  This is
useful for faster booting when we know the initrd is already located
within the reach of the kernel.

Change "norboot" to copy images in order to make it work without
depending on the automatic relocation.

ARM: uniphier: use Image.gz instead Image for booting ARM64 Linux

2017-01-29T11:59:08+00:00

The ARM64 Linux raw image now amounts to 15MB and it is getting
bigger and bigger.  Using Image.gz saves about 8MB.  The cost of
unzip is smaller than what we get by saving the kernel loading
from non-volatile devices.

The ARM32 Linux still uses zImage, a self-decompressor image,
so it should not be affected.

ARM: uniphier: collect SPL CONFIG symbols to the bottom of header

2017-01-29T11:59:08+00:00

For clarification, move CONFIG symbols that affect SPL building
into a single place.  Drop #ifdef CONFIG_SPL ... #endif since it is
harmless to define CONFIG_SPL_... during U-Boot proper building.

ARM: uniphier: detect RAM size by decoding HW register instead of DT

2017-01-29T11:59:08+00:00

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.
