This is correct resolution of BOARD_LATE_INIT for xilinx boards where we
want to disable late init for mini u-boot configurations.

Hi,
As requested while reviewing
452bc121027d ("fdt: fix fdtdec_setup_memory_banksize()")
heres a patch set converting fdtdec_setup_memory_banksize() to use livetree.
v2:
* Added test code for the new function ofnode_by_prop_value()
* The patch "fdt: fdtdec_setup_memory_banksize() use livetree":
Adds ofnode_by_prop_value() to search for nodes with a given property
and value, an ofnode version of fdt_node_offset_by_prop_value().

We left -fdata-sections disabled for x86_64 before because we encountered
random bugs that were at that time inexplicable.
Turns out this really was just side effects of missing .bss* statements
in the linker scripts. With those fixed, we can enable data sections for all
targets.
Signed-off-by: A
While trying to fix efi_loader problems that could only be resolved by enabling
individual function and data sections (commit 7e21fbca26d18 "efi_loader: Rename
sections to allow for implicit data") some cases where .bss was included in
the linker scripts slipped through.
This lead to random breaka
When we build with -fdata-sections we may end up with bss subsections. Our
linker script explicitly lists only a single consecutive bss section though.
Adapt the statement to also include subsections.
This fixes booting efi-x86_app_defconfig.

This adds the support for PDA detection as common code for
Atmel boards.
Using the one wire interface over GPIO , an EEPROM memory is read
and compared to preprogrammed values for PDA screens TM4300, TM7000
and TM7000B.
Once the PDA is detected, an environment variable is set accordingly.

Call the PDA detection mechanism at boot time so we can have
the pda environment variable ready for use.
