The kernel gets much too sad when the ramdisk is loaded too high into the 1GiB
of memory on Raspberry Pi 2:
## Flattened Device Tree blob at 00000100
Booting using the fdt blob at 0x000100
Loading Ramdisk to 39c14000, end 3ab45067 ... OK
Using Device Tree in place at 00000100, end 000045ea
...
[ 0.599346] Unpacking initramfs...
[ 0.602924] Unable to handle kernel paging request at virtual address f9c14000
Placement of the device tree was fixed in 89ca1000 (ARM: rpi: set fdt_high
in the default environment).

CONFIG_SF_DEFAULT_MODE is used to select default SPI mode when using

According to Data Manual(SPRS915P) of AM572x, TI QSPI controller on
DRA74 EVM(rev 1.1+) can support up to 64MHz in MODE-0, whereas MODE-3 is
limited to 48MHz. Hence, switch to MODE-0 for better throughput.
Also, add IODelay parameters for the same.

Boot with the Linux zImage and am3517-evm.dtb pair, when SD/MMC media
is present. This behavior can be overridden by creating a 'uEnv.txt'
file with 'uenvcmd' defined.
To boot an existing 'uImage', create the following 'uEnv.txt':
[start]-----------------------------------------------------------------
loaduimage=fatload mmc 0:1 ${loadaddr} ${bootfile}
uenvcmd=run loaduimage; run mmcargs; bootm ${loadaddr}
[end]-------------------------------------------------------------------

No special reason for the current stack address 0x0ff08000.
Change it to 0x00100000 to simplify the init_page_table.
There are two types of SoCs in terms of the load address of SPL.
[1] PH1-sLD3, PH1-LD4, PH1-sLD8
SPL is loaded at 0x00040000-0x0004ffff
[2] PH1-Pro4, PH1-Pro5, ProXstream2, PH1-LD6b
SPL is loaded at 0x00100000-0x0010ffff
The new stack area (0x000f8000-0x00100000) should be safe for all the
cases.

Since commit ad1ecd2063da ("fdt: Build a U-Boot binary without device
tree") and commit 03c25bcd263a ("fdt: Build an SPL binary without
device tree"), we can use shorter file names for the output images.
The default configuration for UniPhier SoCs enables CONFIG_OF_SEPARATE
and CONFIG_SPL_OF_CONTROL. In this case, spl/u-boot-spl.bin is the
same as spl/u-boot-spl-dtb.bin. Likewise, u-boot.img is the same as
as u-boot-dtb.img. So, this change of the flow has no impact.

Commit 89835b3557fe ("ARM: uniphier: allow to run zImage rather than
uImage") changed the kernel boot commands. Unlike "bootm", "bootz"
does not relocate the kernel image. When the boot device is a NOR
flash, the zImage should be copied from the NOR onto the DRAM before
it is passed to the "bootz" command.

The ARM Linux kernel requires the DT to be in memory accessible early
during the boot process. This always happens naturally on the RPi 1,
since the maximum memory size of 512MiB, and additionally some of that
is reserved for use by the GPU. The RPi 2 has 1GiB of RAM (minus some
GPU usage), and so if the DT is relocated to the top of RAM, Linux cannot
access it. Prevent this from happening by setting fdt_high.
