[PATCH for-7.2 v3 00/20] QMP/HMP: add 'dumpdtb' and 'info fdt' commands

[Daniel Henrique Barboza <danielhb413@gmail.com>]

Hi,

In this new version the most notable changes are:

- removed fdt_pack() from machine specific code. As discussed in the previous
version, the proper use of fdt_pack() would require more work/thought and,
since it's not required for the work we're doing here, it was removed;

- we're now handling string arrays. The previous version was interpreting
all string properties as a single, plain string. We're now dealing with string
arrays instead;

- changed the output format to be more in line with the dts format.

Other small changes were made based on the feeback of the previous version.

Changes from v2:
- patches 1-8:
  - remove fdt_pack() to shrink the FDT before assigning it to ms->fdt
- patch 9:
  - call g_free(ms->fdt) to avoid leaking an old fdt during reset
- patch 10:
  - added a commit msg note about why we're not eliminating spapr->fdt_blob
for machine->fdt at this moment
- patches 11, 12:
  - remove fdt_pack() to shrink the FDT before assigning it to ms->fdt
  - added Alistair's r-b
- patch 13:
  - remove fdt_pack() to shrink the FDT before assigning it to ms->fdt
- patch 14:
  - added a commit msg note about BQL
- patch 15:
  - added a commit msg note about BQL
- patch 16:
  - renamed fdt_prop_is_string to fdt_prop_is_string_array. \0 characters
in the middle of the data array is now legal
  - added a new fdt_prop_format_string_array() to format the string array
  - added a semicolon at the end of the string array
- patch 17:
  - added semicolon at the end of properties
  - use %02x instead of %x to format vals in [] notation
