Poky migration from rocko to warrior

[SOLVED] Note 1

• /dev/xdevfg got obsolete - there's fpga manager instead which cannot load *.bit (only *.bin or *.bit.bin)
• Solution:

Brought back the old driver (drivers/char/xilinx_devcfg.c and edited Kconfig and Makefile)- it works as it used to

[SOLVED] Note 2

• php 5.6.40 - EOL and won't build - mysql supposedly moved header files.
• Solution:

Disabled mysql extension:
To meta-elphel393/recipes-devtools/php/php_5.6.%.bbappend:
    PACKAGECONFIG[mysql] = "--without-mysql --without-mysqli --without-pdo-mysql"
    CFLAGS += " -ldl"

[SOLVED] Note 3

• New package rng-tools is whining: Failed to init entropy source hwrng
• Solution:

Leave as is for now. The full log is:
Initalizing available sources
Failed to init entropy source hwrng
Enabling JITTER rng support
Initalizing entropy source jitter

• Comments:
  • Haven't found if Xilinx uses any driver for /dev/hwrng
  • TODO: Find out if the order of entropy sources can be changed

- Note 4

• php, what's that?
