v4 cover i.MX6: Engicam i.CoreM6/Is.IoT eMMC boot support

From: Jagan Teki <[email protected]>

Changes for v3:
- Rebase on master
- Fix checkpatch.pl Warnings
- Add IMX6_BMODE_UART macro for uart bootmode
- Remove value assignment in enum, since all enum list is order

Changes for v3:
- Update IMX6_BMODE_* shift macros with real number instead of bitops
- %s/IMX6_BMODE_SERIAL/IMX6_BMODE_SERIAL_ROM
- Assign enums with numbers so-that it can easy to see same in RM
- Update board MAINTAINERS file with imx6ul-isiot-emmc.dts file

Changes for v2:
- Rebase on master
- Add Is.IoT eMMC boot patches
- Add few mmc env patches on board

Jagan Teki (15):
imx6: Add imx6_src_get_boot_mode
imx: spl: Update NAND bootmode detection bit

PATCH v4 1/15 imx6: Add imx6_src_get_boot_mode

For i.MX6, the bootmode determine code is part of spl_boot_device, but there is might be a possibility for other part the code need to check the desired boot mode for adding new functionalities like modeboot env variable, or changing boot order etc.

So introduced imx6_src_get_boot_mode which actually reading the boot mode register for desired modes.

More cleanup will be add in future patches.

PATCH v4 2/15 imx: spl: Update NAND bootmode detection bit

In reply to Jagan Teki

BOOT_CFG1[7:4] the NAND boot mode selection is done only when BOOT_CFG1[7] is 1 hence update the NAND boot mode detection bit case. This information available on Table 8-11. NAND Boot eFUSE Descriptions, from IMX6DQRM.

PATCH v4 4/15 imx6: Add src_base structure define macro

Instead of initializing 'struct src' to SRC_BASE_ADDR on every function better to have global define macro.

PATCH v4 5/15 imx6: isiotmx6ul: Update SPL board boot order for eMMC

In reply to Jagan Teki

From: Jagan Teki <[email protected]>

SPL mmc device index is get based on the boot device, like
- BOOT_DEVICE_MMC1 for mmc device 0
- BOOT_DEVICE_MMC2 for mmc device 1

Currently BOOT_DEVICE_MMC1 is setting both SD/eSD and MMC/eMMC boot devices in i.MX, So u-boot is loading from mmc device 0 even "if the board booting from SD/eSD or MMC/eMMC"

So, this patch set BOOT_DEVICE_MMC2 for MMC/eMMC so for MMC/eMMC the u-boot is loading from mmc device 1 and the board file need to take care if the board have different mmc device order intialization.

PATCH v4 7/15 i.MX6UL: isiot: Add modeboot env via board_late_init

In reply to Jagan Teki

From: Jagan Teki <[email protected]>

Add runtime, modeboot env which is setting mmcboot, or nandboot based on the bootdevice so-that conditional macros b/w MMC and NAND for CONFIG_BOOTCOMMAND should be avoided in config files.

PATCH v4 11/15 imx6: icorem6_rqs: Update SPL board boot order for eMMC

In reply to Jagan Teki

SPL mmc device index is get based on the boot device, like
- BOOT_DEVICE_MMC1 for mmc device 0
- BOOT_DEVICE_MMC2 for mmc device 1

Currently BOOT_DEVICE_MMC1 is setting both SD/eSD and MMC/eMMC boot devices in i.MX, So u-boot is loading from mmc device 0 even "if the board booting from SD/eSD or MMC/eMMC"

So, this patch set BOOT_DEVICE_MMC2 for MMC/eMMC so for MMC/eMMC the u-boot is loading from mmc device 1 and the board file need to take care if the board have different mmc device order intialization.

PATCH v4 13/15 i.MX6Q: icorem6_rqs: Add modeboot env via board_late_init

In reply to Jagan Teki

From: Jagan Teki <[email protected]>

Add runtime, modeboot env which is setting mmcboot based on the bootdevice so-that conditional macros for MMC via CONFIG_BOOTCOMMAND should be avoided in config files.

PATCH v4 14/15 i.MX6Q: icorem6_rqs: Add mmc_late_init

In reply to Jagan Teki

From: Jagan Teki <[email protected]>

Let the runtime code can set the mmcdev and mmcroot based on the devno using mmc_get_env_dev instead of defining separately in build-time configs using mmc_late_init func.

I think that's because there is '/dts-v1/;' in the imx6ul-isiot.dtsi file and in imx6ul-isiot-*.dts files.

What is the dtc version used? mine with

dtc -v
Version: DTC 1.4.2-gdaa75e8f

No build issues.

thanks!

I think that's because there is '/dts-v1/;' in the imx6ul-isiot.dtsi file and in imx6ul-isiot-*.dts files.

I cannot confirm this - maybe this depends on dtc compiler. With current DTC from git, everything is compiled.

arch/arm/dts/imx6ul-isiot.dtsi line 43

With this change:

-/dts-v1/;

Anyway, this entry is common to mopst (or all) DTS file. Try simply to grep, and you see that all DTS have it.
