[PATCH 00/17] arm: k3-j721e: Add support for J721E EAIK

[Sinthu Raja]

Hi All,
This series adds support for J721E EAIK. Below is the detailed description
of the J721E SoC and the EAIK board supporting features.

J721E EdgeAI Kit (EAIK) is a low cost, small form factor board designed
for TI’s J721E SoC. TI’s J721E SoC comprises of dual core A72, high
performance vision accelerators, video codec accelerators, latest C71x
and C66x DSP, high bandwidth real-time IPs for capture and display,
GPU, dedicated safety island and security accelerators. The SoC is
power optimized to provide best in class performance for perception,
sensor fusion, localization, path planning tasks in robotics,
industrial and automotive applications.

See J721E Technical Reference Manual (SPRUIL1B, REVISED DECEMBER 2020)
for more details about J721E SoC: http://www.ti.com/lit/pdf/spruil1

J721E EAIK supports the following interfaces:
* 4 GB LPDDR4 RAM
* x1 Gigabit Ethernet interface
* x1 USB 3.0 Type-C port
* x3 USB 3.0 Type-A ports
* x1 PCIe M.2 E Key 
* x1 PCIe M.2 M Key
* 512 Mbit OSPI flash
* x4 CAN-FD interface
* x1 DP interface
* x1 HDMI interface
* x2 CSI2 Camera interface (RPi and TI Camera connector)
* 40-pin Raspberry Pi compatible GPIO header

[Sinthu Raja]

From: Amarnath MB <amarnath.mb@ti.com>

J721E EVM has EEPROM populated at 0x50. J721E EAIK has EEPROM populated
at next address 0x51 in order to be compatible with RBPi. So start
looking for TI specific EEPROM at 0x50, if not found look for EEPROM at
0x51.

[PATCH 09/17] arm: j721e: Add support for selecting DT based on EEPROM

[Sinthu Raja]

From: Amarnath MB <amarnath.mb@ti.com>

Enable support for selecting DTB from FIT within SPL based on the
board name read from EEPROM. This will help to use single defconfig
for both EVM and EAIK.

Also print FDT model name and board name read from EEPROM on SPL debug
console. This is useful to verify that right dtb is loaded in each boot
stage.

[PATCH 13/17] configs: j721e_evm_r5: Enable support for building multiple dtbs into FIT

[Sinthu Raja]

From: Amarnath MB <amarnath.mb@ti.com>

Enable configs for building multiple dtbs into a single fit image
and load the right dtb for next stage. This will help to use same
defconfig for both EVM and EAIK.

[PATCH 15/17] configs: j721e_evm_a72: Align OSPI partitions on erase block boundary

[Sinthu Raja]

From: Amarnath MB <amarnath.mb@ti.com>

S28HS512T on TI EAIK has sector size of 256KB, so update OSPI partition
to align on 256KB sector size. Since the sector size for MT35XU512ABA
on EVM is 128KB, partitions will remain aligned for EVM.

Also, now since the sector size is 256KB ospi.env.backup will collide
with ospi.sysfw, so move ospi.env.backup to the padding space (0x7C0000)
before ospi.rootfs partition.

[Sinthu Raja]

From: Amarnath MB <amarnath.mb@ti.com>

Now that single defconfig can be used for booting J721E EVM and
EAIK, default device tree will not work for selecting dtb for
kernel. Update the findfdt env to select right dtb based on
board_name env variable.
