[PATCH 0/4] rockchip: rk3588: Fix SPI flash bootsource id values
The commit fd6e425be243 ("rockchip: rk3588-rock-5b: Enable boot from SPI NOR flash") added a new BROM_BOOTSOURCE_SPINOR_RK3588 with value 6.
At the time the reason for this new bootsource id value 6 was unknown.
Since then the following bootsource id values have been observed on different RK3588 devices:
- Radxa ROCK 5 Model A - fspim0_pins - rk3588s - Xunlong Orange Pi 5 - fspim0_pins - rk3588s brom_bootdevice_id: 3
- FriendlyElec NanoPC-T6 - fspim1_pins - rk3588 - Xunlong Orange Pi 5 Plus - fspim1_pins - rk3588 brom_bootdevice_id: 4
- Radxa ROCK 5 Model B - fspim2_pins - rk3588 brom_bootdevice_id: 6
It has now been confirmed that the BootRom on RK3588 use different bootsource id values depending on the iomux used by the flash spi controller, and not by the type of spi nor or spi nand flash used.
This series adjusts the bootsource enum values, updates the boot_devices array to fix booting from SPI flash on RK3588 devices using fspim1_pins. It also enable building of a bootable SPI image for affected devices.

I'm a bit wary of two pairs of enums sharing the same value, especially when we want to use them as offset in a static definition of an array.
Should we #ifdef it (meh) for RK3588? Should we add a suffix like before for identifying RK3588-specific options?
At the very least explicit that those are RK3588-specific in a comment for both conflicts (the ones that apply to everything except RK3588 to say to use only for !RK3588, and the ones that apply to RK3588 only)?

Can you say why it is so important to know that given enum is specific to given CPU here in the header file? I think that the enums in the bootrom.h should be as generic as possible.
By using the possible enums in a static array, "solves" the problem of assigning the boot source to specific CPU. There is not need to make such grouping in the bootrom.h.

Which c specification does u-boot follow? Duplicate values in enumerations are explicitly allowed in c as far as I ever have known.

"The use of enumerators with = may produce enumeration constants with values that duplicate other values in the same enumeration." https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2310.pdf
Sorry I wasn't clear. It's less about C specification and more about readability. We could do, but I feel is odd readability-wise is: enum { BROM_BOOTSOURCE_NAND = 1, BROM_BOOTSOURCE_EMMC = 2, BROM_BOOTSOURCE_SPINOR = 3, BROM_BOOTSOURCE_SPINAND = 4, BROM_BOOTSOURCE_SD = 5, BROM_BOOTSOURCE_FSPI_M0_RK3588 = 3, BROM_BOOTSOURCE_FSPI_M1_RK3588 = 4, BROM_BOOTSOURCE_FSPI_M2_RK3588 = 5, BROM_BOOTSOURCE_SPINOR_RK3588 = 6, BROM_BOOTSOURCE_USB = 10, BROM_LAST_BOOTSOURCE = BROM_BOOTSOURCE_USB };
But how many of the other values are still correct for RK3588? The TRM I found quickly does say that NAND and SD/eMMC are valid options, and USB, but I didn't see a table that mapped back to the values here.

I'm a bit wary of two pairs of enums sharing the same value, especially when we want to use them as offset in a static definition of an array.
Should we #ifdef it (meh) for RK3588? Should we add a suffix like before for identifying RK3588-specific options?
At the very least explicit that those are RK3588-specific in a comment for both conflicts (the ones that apply to everything except RK3588 to say to use only for !RK3588, and the ones that apply to RK3588 only)?
Can you say why it is so important to know that given enum is specific to given CPU here in the header file? I think that the enums in the bootrom.h should be as generic as possible.
By using the possible enums in a static array, "solves" the problem of assigning the boot source to specific CPU. There is not need to make such grouping in the bootrom.h.
Do we have any insight as to why Rockchip re-used those values? Looking at the header I see RK3588 has a different SPINOR value than others. Does RK3588 share the same value for other sources? How much of bootrom.h is still correct for RK3588? I'd rather not have to move to having bootrom_${soc}.h like so many other headers are, and if it's just these values, it might be cleaner to #if .. #else .. #endif the whole enum, and then re-evaluate things abased on whatever the next new SoC does here.
Which c specification does u-boot follow? Duplicate values in enumerations are explicitly allowed in c as far as I ever have known.
"The use of enumerators with = may produce enumeration constants with values that duplicate other values in the same enumeration." https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2310.pdf
Sorry I wasn't clear. It's less about C specification and more about readability. We could do, but I feel is odd readability-wise is: enum { BROM_BOOTSOURCE_NAND = 1, BROM_BOOTSOURCE_EMMC = 2, BROM_BOOTSOURCE_SPINOR = 3, BROM_BOOTSOURCE_SPINAND = 4, BROM_BOOTSOURCE_SD = 5, BROM_BOOTSOURCE_FSPI_M0_RK3588 = 3, BROM_BOOTSOURCE_FSPI_M1_RK3588 = 4, BROM_BOOTSOURCE_FSPI_M2_RK3588 = 5, BROM_BOOTSOURCE_SPINOR_RK3588 = 6, BROM_BOOTSOURCE_USB = 10, BROM_LAST_BOOTSOURCE = BROM_BOOTSOURCE_USB };
But how many of the other values are still correct for RK3588? The TRM I found quickly does say that NAND and SD/eMMC are valid options, and USB, but I didn't see a table that mapped back to the values here.
Remaining values that is supported should be same, the only difference for RK3588 is that the old SPINOR=3/SPINAND=4 values now map to flash spi iomux M0 and M1, and compared to bootrom in other SoCs cannot be used to determine if SPI NOR or SPI NAND was the boot source. The new value 6 maps to flash spi iomux M2. What type of flash spi media the device was booted from, nor/nand, does not matter for RK3588.
Guess I can add a enum for the rk3588 FSPI_M0/M1/M2 values directly in rk3588.c where they are used, and when next SoC re-use iomux for flash spi controller they can be moved to bootrom.h.
