[PATCH 3/6] rockchip: mkimage: Print boot0 and boot1 parameters

[Jonas Karlman <jonas@kwiboo.se>]

The v2 image format embeds boot0 and boot1 parameters, the vendor tool
boot_merger may write these parameters based on the rkboot miniall.ini
files.

E.g. a RK3576 boot image may contain a boot1 parameter that signals
BootROM or vendor blobs to use 1 GHz instead of the regular 24 MHz rate
for the high precision timer.

Add support for printing boot0 and boot1 parameters, e.g.:

  > tools/mkimage -l rk3576_idblock_v1.09.107.img
  Rockchip Boot Image (v2)
  Boot1 2: 0x100
  Image 1: 4096 @ 0x1000
  - Load address: 0x3ffc0000
  Image 2: 77824 @ 0x2000
  - Load address: 0x3ff81000
  Image 3: 262144 @ 0x15000
