CTCaer 7d3663616e bdk: sdram: name 2 of the new ram chips 
Not actually validated, but educated guess, since all previous one were correct in the end.
New Micron still unknown, can be guessed but model doesn't exist in any public list.

/*
* Function: sdram_get_params_patched
*
* This code implements a warmboot exploit. Warmboot, that is actually so hot, it burns Nvidia once again.
* If the boot_rom_patch_control's MSB is set, it uses it as an index to
* APB_MISC_BASE (u32 array) and sets it to the value of boot_rom_patch_data.
* (The MSB falls out when it gets multiplied by sizeof(u32)).
* Because the bootrom does not do any boundary checks, it lets us write anywhere and anything.
* Ipatch hardware let us apply 12 changes to the bootrom and can be changed any time.
* The first patch is not needed any more when the exploit is triggered, so we overwrite that.
* 0x10459E is the address where it returns an error when the signature is not valid.
* We change that to MOV R0, #0, so we pass the check.
*
* Note: The modulus in the header must match and validated.
