ti/common: add support for extension_scan_board function

2021-05-13T17:09:09+00:00

The BeagleBone platforms all use a common mechanism to discover and identify extension boards (called "capes"): each extension board has an I2C-connected EEPROM describing itself. This patch implements a generic extension_scan_board() feature that can be used by all BeagleBone platforms to read those I2C EEPROMs and fill in the list of "extension" structures. Following commits will enable this common logic on two BeagleBone platforms. Signed-off-by: Kory Maincent

dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIO

2021-02-21T05:08:00+00:00

Use CONFIG_IS_ENABLED() macro, which provides more convenient way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs for both SPL and U-Boot proper. CONFIG_IS_ENABLED(DM_I2C) expands to: - 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y', - 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y', - 0 otherwise. All occurences were replaced automatically using these bash cmds: $ find . -type f -exec sed -i 's/ifndef CONFIG_DM_I2C/if !CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/ifdef CONFIG_DM_I2C/if CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/defined(CONFIG_DM_I2C)/CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/ifndef CONFIG_DM_I2C_GPIO/if !CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + $ find . -type f -exec sed -i 's/ifdef CONFIG_DM_I2C_GPIO/if CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + $ find . -type f -exec sed -i 's/defined(CONFIG_DM_I2C_GPIO)/CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + Reviewed-by: Heiko Schocher Reviewed-by: Simon Glass Signed-off-by: Igor Opaniuk Reviewed-by: Tom Rini Reviewed-by: Priyanka Jain

ti: common: Remove additional i2c read for board detection

2020-08-31T09:10:28+00:00

There shouldn't be a need to call additional i2c read if above failed already. Based on comment it should be enough to try to detect legacy boards which are mentioned in the comment.

board: ti: board_detect: Add stub functions for EEPROM detection apis

2020-08-11T15:04:46+00:00

Current usage of eeprom apis produce a build failure when CONFIG_TI_I2C_BOARD_DETECT is not defined. Add stub function for these apis to avoid build failures. Reviewed-by: Suman Anna Signed-off-by: Lokesh Vutla

board: ti: common: Fix pointer-bool-conversion warnings

2020-06-16T11:30:02+00:00

When building this code with clang-10 a number of warnings will be generated along the lines of: warning: address of array 'ep->version' will always evaluate to 'true' Convert these checks to checking the strlen of the part of the array we care about. As this array will be null terminated previously by us, this is safe. Cc: Lokesh Vutla Signed-off-by: Tom Rini Reviewed-by: Lokesh Vutla

Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass

board: ti: j721e: Use EEPROM-based board detection

2020-01-20T04:40:28+00:00

The TI J721E EVM system on module (SOM), the common processor board, and the associated daughtercards have on-board I2C-based EEPROMs containing board config data. Use the board detection infrastructure to do the following: 1) Parse the J721E SOM EEPROM and populate items like board name, board HW and SW revision as well as board serial number into the TI common EEPROM data structure residing in SRAM scratch space 2) Check for presence of daughter card(s) by probing associated I2C addresses used for on-board EEPROMs containing daughter card-specific data. If such a card is found, parse the EEPROM data such as for additional Ethernet MAC addresses and populate those into U-Boot accordingly 3) Dynamically apply daughter card DTB overlays to the U-Boot (proper) DTB during SPL execution 4) Dynamically create an U-Boot ENV variable called name_overlays during U-Boot execution containing a list of daugherboard-specific DTB overlays based on daughercards found to be used during Kernel boot. This patch adds support for the J721E system on module boards containing the actual SoC ("J721EX-PM2-SOM", accessed via CONFIG_EEPROM_CHIP_ADDRESS), the common processor board ("J7X-BASE-CPB"), the Quad-Port Ethernet Expansion Board ("J7X-VSC8514-ETH"), the infotainment board ("J7X-INFOTAN-EXP") as well as for the gateway/Ethernet switch/industrial expansion board ("J7X-GESI-EXP").

ti: common: board_detect: Handle EEPROM probe more gracefully

2020-01-20T04:40:28+00:00

Use dm_i2c_probe() rather than i2c_get_chip() when trying to access board-detection EEPROM devices. This has the advantage of more gracefully handling the case when the EEPROM is not present by allowing to exit the function early rather than failing and outputting an error message on the I2C transactions that follow.
