data section via "INSERT BEFORE .data;". Running readelf -S on sandbox

This means that the __bss_start assignment in the linker script is bogus,
as the actual bss section start is located elsewhere. Remove this
assignment, as the __bss_start symbol is not used on sandbox anyway.

init_func_i2c is wrapped only by "#if defined(CONFIG_SYS_I2C)". Because

Some of these were not converted when binman moved to use absolute paths.

Signed-off-by: Simon Glass <sjg@chromium.org>
When binman is installed its main program is in a different directory
to its modules. This means that __file__ is different and we cannot use
it to obtain the path to etype/ from main.py
To fix this, move the function to the 'control' module, since it is
installed with all the other modules, including the etype/ directory.

When you enable CONFIG_OF_LIVE, you will end up with a lot of

To help this tedious work, this commit converts devfdt_get_addr_ptr()
to dev_read_addr_ptr() by coccinelle. I also removed redundant casts
because dev_read_addr_ptr() returns an opaque pointer.
To generate this commit, I ran the following semantic patch

In the case of the live tree ofnode_read_addr_cells() and

This patch fixes the incorrect parsing of the device tree leading to
'saveenv' failing on qemu_arm64_defconfig.
For testing qemu-system-aarch64 has to be called with

On systems with multiple memory nodes finding out the first memory node by
fdtdec_setup_mem_size_base() is not enough because this memory can be above
actual U-Boot VA mapping. Currently only mapping till 39bit is supported
(Full 44bit mapping was removed by commit 7985cdf74b ("arm64: Remove
non-full-va map code")).
If DT starts with the first memory node above 39bit address then system can
be unpredictable.
The function is available only when multiple memory bank support is
enabled.
Calling fdtdec_setup_memory_banksize() from dram_init() is not possible
because fdtdec_setup_memory_banksize() is saving dram information to bd
structure which is placed on stack but not initialized at this time. Also
