commit e27bddff4b97 ("imx8m: Restrict usable memory to space below 4G boundary")
tried to adjust the usable memory limits on a 4GB boundary.
ram_top is described as 'top address of RAM used by U-Boot' and we want
to preserve that. This is defined as a phys_addr_t and unfortunately
its size differs across architectures. This has lead us to a weird
state where 32bit boards define it 'SZ_4GB - 1' and 64bit boards as
'SZ_4GB' unless it was otherwise defined.
With some recent LMB changes and specifically
commit 1a48b0be93d4 ("lmb: prohibit allocations above ram_top even from same bank")
the board fails to boot properly although the commit above is correct
since it's making sure that no memory above ram_top is usable -- but
added to our memory map so EFI can hand it over to the booted OS.
The reason for that is that during the LMB init we add all usable memory
in lmb_add_memory(). In that function any memory above ram_top gets added
as 'reserved' for LMB. With the current values tha's set to 0xFFFF_FFFF
for this board. Later LMB is trying to protect the memory area U-Boot lives
in with lmb_reserve_common(). The latter fails though since it tries to
add U-Boot top (which is 0xFFFF_FFFF as well) to U-Boot 'bottom'. This call
will fail since 1 byte of that memory range is already marked as 'reserved'.
Since we are close to the release, LMB seems to assume that the address
is rounded up and is the 'next address' and so does parsing and adding
memory ranges from DT files, bump the ram_top of the board by 1byte.
In the long run we should change all of the above and have 32b and 64b
platforms define ram_top identically.
Add a Fixes tag although the commit is correct, so people can figure out
the broken scenarios in the future.

Starting with v2024.10 dev_iommu_dma_unmap calls during device removal
trigger a NULL pointer dereference in the Apple dart iommu driver. The
iommu device is removed before its user. The sparsely used DM_FLAG_VITAL
flag is intended to describe this dependency. Add it to the driver.
Adding this flag is unfortunately not enough since the boot routines
except the arm one simply remove all drivers. Add and use a new function
which calls
dm_remove_devioce_flags(DM_REMOVE_ACTIVE_ALL | DM_REMOVE_NON_VITAL);
dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);
to ensure this order dependency is head consistently.
Link: https://lore.kernel.org/r/20241123-iommu_apple_dart_ordering-v2-0-cc2ade6dde97@jannau.net
This replaces dm_remove_devices_flags() calls in all boot
implementations to ensure non vital devices are consistently removed
first. All boot implementation except arch/arm/lib/bootm.c currently
just call dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL). This can result
in crashes when dependencies between devices exists. The driver model's
design document describes DM_FLAG_VITAL as "indicates that the device is
'vital' to the operation of other devices". Device removal at boot
should follow this.
Instead of adding dm_remove_devices_flags() with (DM_REMOVE_ACTIVE_ALL |
DM_REMOVE_NON_VITAL) everywhere add dm_remove_devices_active() which
does this.
Fixes a NULL pointer deref in the apple dart IOMMU driver during EFI
boot. The xhci-pci (driver which depends on the IOMMU to work) removes
its mapping on removal. This explodes when the IOMMU device was removed
first.
dm_remove_devices_flags() is kept since it is used for testing of
device_remove() calls in dm.

If TPL_GPIO and TPL_PINCTRL_ROCKCHIP are enabled and a sysreset-gpio is
provided in the TPL Device Tree, this will trigger a system reset
similar to what's currently been done in SPL whenever the RK3399 "warm"
boots. Because there's currently only one user of sysreset-gpio logic,
and TPL is enabled on that board, so let's migrate the logic and that
board to do it in TPL.
There are three reasons for moving this earlier:
- faster boot time as we don't need to reach SPL to be able to reset the
system on a condition we know is already met in TPL,
- have less code to be impacted by the issue this system reset works
around (that is, "unclean" SoC registers after a reboot),
- less confusion around the reason for restarting. Indeed when done from
SPL, the following log can be observed:
