The setup of global variable mem_map was moved into enable_caches()
by commit a70c75cabae1 ("board: developerbox: move mem_map setup later")
since U-Boot was directly booted from NOR flash in XIP
and bss is not yet available in dram_init() at that time.
This has a problem, mem_map variable is used by
the get_page_table_size() to calculate the page table size,
but get_page_table_size() is called earlier than enable_caches()
which fills mem_map variable. With that, U-Boot fails to boot when
64GB DIMM is installed.
Currently U-Boot on the Developerbox board is not booted in XIP
and bss is available in dram_init(), let's move mem_map setup
in dram_init().

One fix makes the reboot more robust on some older board, another one
stabilises the initial clock setup on the A10/A20.
Two patches make sure our DRAM init does not actually change the content
of the DRAM array, which allows to use DRAM for Linux' pstore
functionality.
We get SPI support for U-Boot proper for one more SoC, that patch was
lingering around for a while, and should not affect other SoCs, so I am
merging this now.
As an added bonus, we get the defconfig file for a new board, the DT was
already synced from the kernel tree.
The CI looked happy with changes, and I tested them on five different
boards with different SoCs.
Add a config fragment with required differences for booting from spi
flash instead of sd-card (default).
Settings for environment location are based on vendor u-boot:
https://github.com/kobol-io/u-boot/blob/helios4/include/configs/helios4.h#L59
