u-boot adds reserve-memory node, if it's missing, with following
properties:
```
reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;
}
```
But with these default address-cells and size-cells values, pstore
isn't working on A64. Root node for A64 defines 'address-cells' and
'size-cells' as 1.
dtc complains if reserved-memory has different address-cells and
size-cells.
```
Warning (ranges_format): /reserved-memory:ranges: empty "ranges"
property but its #address-cells (2) differs from / (1)
```
This patch takes into account address-cells and size-cells of the root
node and uses them as values for new reserved-memory node.

The pstore command tries to create a reserved-memory node but fails if
it is already present with:
Add 'reserved-memory' node failed: FDT_ERR_EXISTS
This patch creates the node only if it does not exist and adapts the reg
values sizes depending on already present #address-cells and #size-cells
values.

It is a pain to have to specify the value 10 in each call. Add a new
dectoul() function and update the code to use it.

It is a pain to have to specify the value 16 in each call. Add a new

Add a proper comment to simple_strtoul() while we are here.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

To simplify configuration and keep synchronized the PStore/Ramoops between
U-Boot and the Linux kernel, this commit dynamically adds the Ramoops
parameters defined in the U-Boot session to the Device Tree.

This patch adds a new pstore command allowing to display or save ramoops
logs (oops, panic, console, ftrace and user) generated by a previous
kernel crash.
PStore parameters can be set in U-Boot configuration file, or at run-time
using "pstore set" command. Records size should be the same as the ones
used by kernel, and should be a power of 2.
This command allows:
- to display uncompressed logs
- to save compressed or uncompressed logs, compressed logs are saved as a
compressed stream, it may need some work to be able to decompress it,
e.g. adding a fake header:
"printf "\x1f\x8b\x08\x00\x00\x00\x00\x00\x00\x00" |
cat - dmesg-ramoops-0.enc.z | gzip -dc"
- ECC part is not used to check memory corruption
- only 1st FTrace log is displayed or saved
