Add EEPROM detection initialisation for phyCORE-i.MX8MM.
Signed-off-by: Yunus Bas <[email protected]>
|
|
The phyCORE-i.MX 93 is available in various variants (e.g. different ram
sizes, eMMC HS400 yes/no). Enable hardware introspection for the
imx93-phyboard-segin_defconfig, so that during startup the SOM module
variant can be detected, and the hardware can be configured accordingly.
The resulting SPL and u-boot binary shall able to boot each
phyCORE-i.MX 93 module variant on each carrier board. Finally rename
imx93-phyboard-segin_defconfig to imx93-phycore_defconfig, to highlight
its SOM scope.

The phyCORE-i.MX 93 is available in various variants. Relevant variant
options for the spl/u-boot are:
- with or without HS400 support for the eMMC
- with 1GB ram chip, or 2GB ram chip
The phyCORE's eeprom contains all information about the existing variant
options. Add evaluation of the eeprom data to the spl/u-boot to
enable/disable HS400 and to select the appropriate ram configuration at
startup.

The phyCORE-i.MX 93 is available with a 1GB ram chip or a 2GB ram chip.
Add the ram timings for the 2GB chip, in form of a diff compared
to the existing LPDDR4X 1GB timings. With that, the SPL can select the
appropriate timings at startup.
Update also the 1GB ram timings with new version of the DDR Tool.

Our SoMs are available in multiple configurations, managed via device
tree overlays. To determine the specific variant in use, we read the
EEPROM and apply the appropriate overlays during boot to the device tree
used by the OS.

Since we use SPEED GRADE fuse to set A55 frequency, remove the
set_arm_core_low_drive_clk function which has hard coded frequency.
And adjust clock_init called sequence and split it to early and late
functions.
Set the authen register in early function, because CCF driver checks
NS bit.
Set bus and core clock in late function, because the fuse read and
SoC type/rev depend on ELE.

This patch stack extends the phyCORE-AM62x/AM64x U-Boot by following boot
sources:
- Load U-Boot with USB DFU
- Load a Linux and initramfs from OSPI/QSPI NOR flash
- Load a Linux and rootfs from Network
Moreover, it adds required changes to the environment to boot an A/B
system with RAUC and includes some minor fixes.

Include the boot logic to boot via Network or from a OSPI/QSPI
NOR flash. Moreover, set all required variables to both boot
methods to the environment.
Note: The phyBOARD-Electra AM64x is not able to load the U-Boot
via Network. However, it's still possible to load the kernel.

There is no need to reread the EEPROM multiple times in different stages
to detect the RAM size. We can do this once at an early stage and let
higher stages decode memory nodes using fdtdec.

This patch series adds support for the EEPROM v3 API.
V3 is backwards compatible to V2 and therefore, the V2 image still
exists at the beginning. Only the API version changed from 2 to 3.
V3 is a block-based memory layout organized as singled-linked list
with different types of blocks. This is a more flexible approach and
allows us to extend it by more block types in the future.
The V3 data starts with a 8-byte large header which defines the
block count (u8), V3 subversion (u8) and data payload length (u16).
Additionally the header contains a CRC8 checksum a 3 reserved bytes.
Each block starts with a 4-byte large header which defined the
block type (u8), the absolute address of the next block (u16) and a
CRC8 checksum. The content itself is defined via the block type and
we currently have 2 different types:
1) MAC: Contains the Ethernet interface number (u8), MAC address
(6 x u8) and a CRC8 checksum.

This API is based on a block structure with a 8 Byte large

directly after v2.

Ehternet interface number, a MAC address and a CRC checksum over the
MAC payload.
