mb/google/dedede/var/waddledoo: Use auto-generated Makefile.inc using gen_part_id.go
This change adds mem_list_variant.txt that contains the list of
memory parts used by waddledoo and Makefile.inc generated by
gen_part_id.go using mem_list_variant.txt.
In the final change of the series, all dedede variants will be
switched from using the current SPDs to new auto-generated SPDs.
Differences in auto-generated SPD from current SPD are as follows:
Part: MT53E512M32D2NP-046 WT:E
Byte# Current New Explanation
4 0x15 0x16 This part has only 1 die. Hence,
density per die is 16Gb.
6 0x90 0x04 1 die in package and 2 channels per
die.
9 0x40 0x00 Unused by MRC.
19 0x0F 0xFF As per JEDEC spec, tckMax should be
100ns. So, value should be 0xFF as
per datasheet.
123 0x00 0xE5 Fine offset for taa. Expected value
is 0xE5 as per datasheet.
125 0xE1 0xE0 Fine offset for tckMin. As per
datasheet tckMin is 0.468ns. So, this
comes out to be 0xE0.
Additionally, manufacturer name bytes are set to 0.
Part: NT6AP256T32AV-J2
Waddledoo started assigning DRAM part IDs from 1. So, this change
fills in Nanya part as ID 0 (though it is currently unused).

coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
coreboot was formerly known as LinuxBIOS.
After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.
See https://www.coreboot.org/Payloads for a list of supported payloads.
coreboot supports a wide range of chipsets, devices, and mainboards.
For details please consult:
ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case).Optional:
make menuconfig and make nconfig)Please consult https://www.coreboot.org/Build_HOWTO for details.
If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.
Please see https://www.coreboot.org/QEMU for details.
