IFC NOR flash base address of ls2088a is 0x85000,
and env crc offset size is 0x50, so fix the macro
CONFIG_ENV_ADDR to fix synchronous exception(access illegal address)
Fixes: 59071804c1 ("configs: ls2080a: Correct ENV_ADDR value")

Hi Tom,
please pull the next batch of Marvell Armada related patches, mostly
the ones dropped last time because of Xilinx issue (fixed now). Here

Hi,
When doing linux kernel work, the public-inbox archives at
lore.kernel.org are really useful.
- excellent search features
- stable links of the form lore.kernel.org//
- nice overview of threads
- ability to, with the b4 tool, download patches or whole series by
msg-id, and logic to compare

Currently we use incremental linking (ld -r) to link several object
files from one directory into one built-in.o object file containing the
linked code from that directory (and its subdirectories).
Linux has, some time ago, moved to thin archives instead.
Thin archives are archives (.a) that do
When apf27_defconfig is built with LTO, linking complains about
undefined reference to `nand_boot`. This is because it is referenced
from inline assembly. Make it visible.

When using LTO, we can throw away the --gc-sections flag, but only if
