[Buildroot] [PATCH v2 0/4] Add support for rk3399 based targets

[Suniel Mahesh]

This patch series adds support for targets from friendlyarm, pine64 and orangepi,
based on rk3399 SOC.

Merged two patch series at https://patchwork.ozlabs.org/project/buildroot/list/?series=174279,
into this series.

patch #1, #2, are basically a resend. patch #3, #4 are new patches.

Changes for v2:
- Done few changes based on Thomas Pettazonni suggestions and 
  mailing list
- bumped linux version from 5.4.46 to 5.8.2
- bumped u-boot version from 2020.04 to 2020.07
- recent series is at:

[Buildroot] [PATCH v2 1/4] configs/rockpro64: new defconfig

[Suniel Mahesh]

A defconfig for the rockpro64 was added in
59e1077b4ebe79622a454b0a8a840e4349a0440d, but then removed
in 10f49213b7e2837ae6ed63fc16fbdaa954ecd87f because an ARM32
compiler was needed to build ATF, and this was not supported
back then.

Now, since package/arm-gnu-a-toolchain/ has been added, this
defconfig can be re-introduced.

Following new changes are introduced in comparision with the
older changeset:

    - renamed defconfig from pine64_rockpro64 to rockpro64
    - updated readme
    - using a GPT partition layout
    - update defconfig to build ATF
    - bump u-boot to 2020.07
    - bump linux to 5.8.2

[Buildroot] [PATCH v2 3/4] configs/nanopi_m4: new defconfig

[Suniel Mahesh]

A defconfig for the friendlyarm nanopi-m4 was added in
493c3979a4def978a1137cf8543bf0de50d2615e, but then removed
in a24bd8936f57a590f810e14d7828cf1bddce580e because an ARM32
compiler was needed to build ATF, and this was not supported
back then.

Now, since package/arm-gnu-a-toolchain/ has been added, this
defconfig can be re-introduced.

Following new changes are introduced in comparision with the
older changeset:
        - readme updated
        - GPT partition layout
        - update defconfig to build ATF
        - bump u-boot to 2020.07
        - bump linux to 5.8.2

[Buildroot] [PATCH v2 4/4] configs/nanopc_t4: new defconfig

[Suniel Mahesh]

A defconfig for the friendlyarm nanopc-t4 was added in
c23895f06e0988319a1959764a402b57bc21ffaf, but then removed
in 8efd4463f78fd68c85b45cc0da347dfb805abb7e because an ARM32
compiler was needed to build ATF, and this was not supported
back then.

Now, since package/arm-gnu-a-toolchain/ has been added, this
defconfig can be re-introduced.

Following new changes are introduced in comparision with the
older changeset:

	- updated readme
	- GPT partition layout is being used
	- update defconfig to build ATF
	- bump u-boot to 2020.07
	- bump linux to 5.8.2

 Please always use a fixed version (i.e. CUSTOM_VERSION with 2020.07 as the
version number).

 This is a blind option, after running a config it will be reset to no. It is
set by some of the other options that require python packages.

 Just to be sure: you really do need python to build U-Boot in this config?


 I've made those two fixes in all four patches and applied to master, thanks.

 Arnout

Yes it's a blind option, I have done a quick test to confirm. It is not needed.
Thanks for the correction.
