[U-Boot] [PATCH 00/10] i.MX8QXP: MEK: support SPL

[U-Boot] [PATCH 00/10] i.MX8QXP: MEK: support SPL

[Peng Fan]

This is to support SPL for i.MX8QXP MEK board and default support SPL.
In this patchset, use SPL FIT, but actually we could not use SPL FIT
for secure boot, in NXP vendor tree, there is another format called
container, NXP use SPL + container for secure boot. The container
support is on my TODO list. But to make SPL work in upstream, use
SPL FIT here.

Peng Fan (10):
  imx8qxp: add SUPPORT_SPL option
  imx8: scu: use dedicated MU for SPL
  arm: imx: build mach-imx for i.MX8
  gpio: introduce CONFIG_SPL_DM_PCA953X
  spl: imx8: add spl boot device
  dts: imx8qxp-mek: introduce u-boot dtsi
  imx: mkimage_fit_atf: introduce BL33_BASE_ADDR
  imx: build flash.bin for i.MX8
  imx8qxp: mek: default enable SPL
  imx8qxp: mek: update README

[U-Boot] [PATCH 02/10] imx8: scu: use dedicated MU for SPL

[Peng Fan]

SPL runs in EL3 mode, except MU0_A, others are not powered on,
and could not be used. However normal U-Boot use MU1_A, so we
could not reuse the one in dts. And we could not replace the one
in dts with MU0_A, because MU0_A is reserved in secure world.

[U-Boot] [PATCH 09/10] imx8qxp: mek: default enable SPL

[Peng Fan]

Enable SPL for i.MX8QXP MEK, and currently use SPL FIT.
The SPL enable SPL_DM to use MMC/PINCTRL/POWER DOMAIN/CLK.

Note: SPL FIT could not support secure boot chain, because i.MX8/8X
only support i.MX container format. This container format has
not been upstreamed, so we use FIT for now. When SPL container
supported, we could switch to that.
