[U-Boot] [u-boot PATCH v2 0/8] am57xx-idk LCD and am571x-idk 6 port ethernet pinmux
Hi,
This series contains
- Support am571x-idk LCD vs 6 port ethernet pinmux configuration. - AM57xx-idk LCD detection support. - K2G: pick up PRUSS ethernet MAC addresses from board EEPROM.
Changelog: v2: - avoid using __maybe_unused. - moved EEPROM address configuration to Kconfig. - LCD detection patch no longer update device tree.
cheers, -roger

The board can support either ICSS1 Ethernet ports or LCD based on J51 jumper. Factory default is ICSS1 Ethernet ports (i.e. Jumper not populated).
Use the GPIO to detect the jumper setting and configure the pinmux accordingly. Also select the right DT blob based on the chosen configuration.
J51 absent -> ICSS1 Ethernet, no LCD on VOUT -> am571x-idk.dtb J51 present -> LCD on VOUT, no ICSS1 Ethernet -> am571x-idk-lcd-osd.dtb
At present we only support the assume it is the Legacy LCD. LCD detection mechanism needs to be added later to differentiate between legacy vs new LCD.
For ICSS1 Ethernet pins use the following convention to set the pinmux as PMT data is not yet finalized.
- If pin is output, set as PIN_OUTPUT - If pin is input and external pull resistor present set as PIN_INPUT - If pin is input and external pull resistor absent, set pull to same as that of the external PHY's internall pull. - Do not use SLEW_CONTROLon any pin.

Use the same convention that was used for ICSS1 Ethernet - If pin is output, set as PIN_OUTPUT - If pin is input and external pull resistor present set as PIN_INPUT - If pin is input and external pull resistor absent, set pull to same as that of the external PHY's internall pull.

AM571x IDK and AM572x IDK have optional LCD Kits that can be purchased. These can be one of OSD101T2045 or the newer OSD101T2587. The LCD panel itself has no registers that can be used to identify the panel, however, the touchscreen controllers on the panels are different.
Hence to ease user experience, we can use the touch screen controller's ID information to detect what kind of panel we use and select the appropriate kernel dtb for the platform configuration.
NOTE: AM572x IDK default configuration is for LCD Connectivity, however the AM571x IDK has a jumper (J51) that needs to be mounted for the IDK to operate with LCD (Vs two PRUSS ethernet port option).
Touchscreen ID information is documented in: http://www.osddisplays.com/TI/OSD101T2587-53TS_A.1.pdf

IMO, these should be placed in board/ti/common/Kconfig. Also need not specify the value explicitly in defconfig if default value is used.

The Kconfig file may need some minor tweaks / dependencies added to be used on keystone, and long term we'll be doing all of those "config SPL_FOO\ndefault y" entries another way. The NAND entry could be changed (but you'll need to test, and shoving a test branch at travis-ci is an easy way to test) to be instead of 'default y' be 'default CMD_NAND' I think.

It starts to look ugly if I add conditions in the Kconfig file. Why are we setting default y to various SPL_* options in this file? Shouldn't the board config file explicitly set the values? e.g. some TI board might not need SPL_I2C and other might need it.

IMO, these should be placed in board/ti/common/Kconfig. Also need not specify the value explicitly in defconfig if default value is used.

The Kconfig file may need some minor tweaks / dependencies added to be used on keystone, and long term we'll be doing all of those "config SPL_FOO\ndefault y" entries another way.

Until the 'imply' keyword comes in to Kconfig we're left with a few different ugly options in order to avoid having to make the defconfig files themselves unwieldy. A 'default y' does not make it impossible to disable the feature, but changing the default here potentially easier than setting it to N in the various k2 defconfig files, for example.
PRU ethernet MAC address range is present in the board EEPROM. Parse it and setup eth?addr environment variables.

This can be dropped as these are the default values. Rest looks good to me.
