/*
|
|
* Memory configuration.
|
|
*
|
|
* The prior stage BOLT bootloader sets up memory for us.
|
|
*
|
|
* An example boot memory layout after loading everything is:
|
|
*
|
|
* 0x0000 8000 vmlinux.bin.gz
|
|
* : [~31 MiB uncompressed max]
|
|
* 0x01ef f000 FIT containing signed public key
|
|
* : [~2 KiB in size]
|
|
* 0x01f0 0000 DTB copied from prior-stage-provided region
|
|
* : [~1 MiB max]
|
|
* 0x0200 0000 FIT containing ramdisk and device tree
|
|
* : initramfs.cpio.gz
|
|
* : [~208 MiB uncompressed max, to CMA/bmem low address]
|
|
* : [~80 MiB compressed max, to PSB low address]
|
|
* : device tree binary
|
|
* : [~60 KiB]
|
|
* 0x0700 0000 Prior stage bootloader (PSB)
|
|
* :
|
|
* 0x0761 7000 Prior-stage-provided device tree binary (DTB)
|
|
* : [~40 KiB in size]
|
|
* 0x0f00 0000 Contiguous memory allocator (CMA/bmem) low address
|
|
* :
|
|
* 0x8010 0000 U-Boot code at ELF load address
|
|
* : [~500 KiB in size, stripped]
|
|
* 0xc000 0000 Top of RAM
|
|
*
|
|
* Setting gd->relocaddr to CONFIG_SYS_TEXT_BASE in dram_init_banksize
|
|
* prevents U-Boot from relocating itself when it is run as an ELF
|
|
* program by the prior stage bootloader.
|
|
*
|
|
* We want to keep the ramdisk and FDT in the FIT image in-place, to
|
|
* accommodate stblinux's bmem and CMA regions. To accomplish this,
|
|
* we set initrd_high and fdt_high to 0xffffffff, and the load and
|
|
* entry addresses of the FIT ramdisk entry to 0x0.
|
|
*
|
|
* Overwriting the prior stage bootloader causes memory instability,
|
|
* so the compressed initramfs needs to fit between the load address
|
|
* and the PSB low address. In BOLT's default configuration this
|
|
* limits the compressed size of the initramfs to approximately 80
|
|
* MiB. However, BOLT can be configured to allow loading larger
|
|
* initramfs images, in which case this limitation is eliminated.
