rpi: Enable DRAM bank initialization on arm64

2019-12-11T09:14:12+00:00

Up to now we only update the DRAM banks when we are define
CONFIG_BCM2711. But our one binary approach uses a config that supports
BCM2837 and BCM2711. As a result we only see one gibibyte of RAM on
Raspberry Pi 4, even if it has more RAM.
Fix this by calling dram_init_banksize.

rpi: fix dram bank initialization

2019-12-11T09:14:12+00:00

To update the dram bank information from device-tree we use
fdtdec_decode_ram_size() which expectes the the size-cells and
address-cells to be defined in the memory node. For normal system RAM
these values are defined in the root node. When the values differ from
the default values defined in the spec, we can end up with wrong RAM
bank information.

Switch to the "standard" way to update the RAM bank information to
avoid this.

common: Move board_get_usable_ram_top() out of common.h

2019-12-02T23:25:04+00:00

Move this function into init.h which seems to be designed for this sort
of thing. Also update the header to declare struct global_data so that it
can be included without global_data.h being needed.

ARM: bcm283x: Set memory map at run-time

2019-11-24T09:46:28+00:00

For bcm283x based on arm64 we also have to change the mm_region.
Add assign this in mach_cpu_init() so we can create now one binary
for RPi3 and RPi4.

rpi: push fw_dtb_pointer in the .data section

2019-11-24T09:46:27+00:00

The fw_dtb_pointer was defined in the assembly code, which makes him
live in section .text_rest
Put that's not necessary, we can push the variable in the .data section.

This will prevent relocation errors like:
board/raspberrypi/rpi/rpi.c:317:(.text.board_get_usable_ram_top+0x8):
relocation truncated to fit: R_AARCH64_LDST64_ABS_LO12_NC against symbol
`fw_dtb_pointer' defined in .text section in board/raspberrypi/rpi/built-in.o

rpi4: enable dram bank initialization

2019-10-01T09:14:47+00:00

When booting through the efi stub, the memory map get's created by
reading the dram bank information. Depending on the version of the RPi4
this information changes. Read the device tree to initialize the dram
bank data structure. This way the kernel is able to access the whole
range of available memory.

env: Drop environment.h header file where not needed

2019-08-11T20:43:41+00:00

This header file is now only used by files that access internal
environment features. Drop it from various places where it is not needed.
