This is an updated EEPROM-based board detection series that can applied
if staged with other patches in the sequence proposed earlier [1].
For completeness here is the proposed sequence again, avoiding merge
conflicts, but this time from the perspective of this patch series.
Step 1) Faiz' "Add Support for eMMC in Am65x-evm" series [2]. It needs
a small update to actuall allow for eMMC boot I posted earlier.
Step 2) The updated (v2) SYSFW loader series just posted [3]
Step 3) The updated AM654x EEPROM support proposed with this series
Step 4) An updated version of Lokesh's "arm: k3: Allow for exclusive
and shared device requests" series [4]. In addition to a rebase
such an updated series should include updating power domain
properties for devices that were added during the previous
steps.
Step 5) An updated version of Lokesh's "arm: k3: arm64: Initial support
Texas Instrument's J721E Platform" series [5] also adding
in the few lines of codes to leverage SYSFW.
Step 6 & beyond) Various rproc patches, etc.
Changes since v2:
- Re-based for proposed staging K3 AM654x patch staging sequence
Changes since initial submission:
- Re-based onto latest 'master' branch
- Collected all review tags
- Re-tested

Only U-Boot specifc DT properties or overrides, must be in -u-boot.dtsi.
Pinctrl nodes does not belong here. Now that pinctrl nodes are in kernel
DT, there is no reason to be keep these in -u-boot.dtsi. Move them to
proper places so that it would ease copying DT entries from kernel DT.

To: u-boot
To enable the use of an EEPROM-based board detection scheme we need to
be able to access the I2C bus associated with the EEPROMs across all
3 stages of U-Boot: R5 SPL, A53 SPL, and A53 U-Boot (proper). So go
ahead and add/update the wkup_i2c0 peripheral module DTS definitions
and its associated pinmux node accordingly.

The AM654 base board has a TCA9554/PCA9554-type GPIO expander on the
wkup_i2c0 bus at address 0x38 that is used to detect the presence of
daughter cards. Add a respective DTS description of this expander
to enable its use.

The malloc pool used before relocation is getting tight leading to
out of memory errors doing certain DM-related calls. Since we are
running the A53 SPL out of DDR let's just go ahead and bump its size
as used in U-Boot proper as well as SPL (via Kconfig default value)
from 8KB to 32KB.

The board detection scheme employed on various TI EVMs makes use of
SRAM scratch space to share data read from an on-board EEPROM between
the different bootloading stages. Map the associated definition that's
used to locate this data into the SRAM scratch space we use on AM654x.

To: u-boot
The AM654x EVM based on the TI K3 family of SoCs have an updated board
detection EEPROM structure, now comprising variable-sized TLV-type
records, containing a superset of what is already being provided on
earlier platforms such as DRA7. Add basic support for parsing the new
data structures contained on the base board into the common TI EEPROM
structure while also providing infrastructure that can be used later on
to parse data from additional EEPROMs such as the ones that are used on
daughtercards for this platform.

From: Andreas Dannenberg @ 2019-06-04 23:08 UTC (permalink / raw)
To: u-boot
The AM654x EVM based on the TI K3 family of SoCs has an updated board
detection EEPROM structure that contains a TLV record of dedicated MAC
addresses rather than a range of MAC addresses as it was used on earlier
platforms such as DRA7. Add a basic function that allows us setting up
Ethernet MAC addresses into the U-Boot environment based on the MAC
address record contained in the common TI EEPROM structure.

From: Andreas Dannenberg @ 2019-06-04 23:08 UTC (permalink / raw)
To: u-boot
The TI AM654x EVM base board and the associated daughtercards have on-
board I2C-based EEPROMs containing board configuration data. Use the
board detection infrastructure introduced earlier to do the following:
1) Parse the AM654x EVM base board EEPROM and populate items like board
name and MAC addresses into the TI common EEPROM data structure
residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing the associated
presence signals via an I2C-based GPIO expander. Then, if such a
card is found, parse the data such as additional Ethernet MAC
addresses from its on-board EEPROM and populate into U-Boot
accordingly
3) Dynamically create an U-Boot ENV variable called overlay_files
containing a list of daugherboard-specific DTB overlays based on
daughercards found.
This patch adds support for the AM654x base board ("AM6-COMPROCEVM")
as well as for the IDK ("AM6-IDKAPPEVM"), OLDI LCD ("OLDI-LCD1EVM")
PCIe/USB3.0 ("SER-PCIEUSBEVM"), 2 Lane PCIe/USB2.0 ("SER-PCIE2LEVM"),
and general purpuse ("AM6-GPAPPEVM") daughtercards.
