efi_loader: Reserve unaccessible memory
On some systems, not all RAM may be usable within U-Boot. Maybe the
memory maps are incomplete, maybe it's used as workaround for broken
DMA. But whatever the reason may be, a platform can say that it does
not wish to have its RAM accessed above a certain address by defining
board_get_usable_ram_top().
In the efi_loader world, we ignored that hint, mostly because very few
boards actually have real restrictions around this.
So let's honor the board's wish to not access high addresses during
boot time. The best way to do so is by indicating the respective pages
as "allocated by firmware". That way, Operating Systems will still
use the pages after boot, but before boot no allocation will use them.

efi_loader: Ensure memory allocations are page aligned
When the max_addr parameter of efi_find_free_memory() is within bounds
of an existing map and fits the reservation, we just return that address
as allocation value.
That breaks however if max_addr is not page aligned. So ensure that it
always comes to us page aligned, simplifying the allocation logic.
Without this, I've seen breakage where we were allocating pages at -1U
(32bit) which fits into a region that spans beyond 0x100000000. In that
case, we would return 0xffffffff as a valid memory allocation, although
we usually do guarantee they are all page aligned.
Fix this by aligning the max address argument always.
With RELA absolute relocations, the relocation target contains our link
offset which we need to remove from the equation again. We did this
properly in the relative relocation path, but not in the absolute one.
So let's do this for the absolute one as well. That way, u-boot can have
a TEXT_OFFSET of != 0 and still relocate itself properly.
This fixes a bug where efi_loader did not work on the RISC-V QEMU port.
With this patch, I can successfully run UEFI applications on the RISC-V
QEMU port.

usb: Do not compile USB_STORAGE with BLK && !DM_USB
The USB storage driver does not compile when CONFIG_BLK is set,
but DM_USB is not set, as we're missing the DM device links for
CONFIG_BLK enabled code paths.
So far it looks like nobody fell into this trap, because no board
enabled CONFIG_BLK and CONFIG_USB_STORAGE while not enabling
CONFIG_DM_USB, but we should still reflect that dependency properly
in Kconfig so that implicit enabling of CONFIG_USB_STORAGE works.
When an operating system started via bootefi tries to reset or power off
this is done by calling the EFI runtime ResetSystem(). On most ARMv8 system
the actual reset relies on PSCI. Depending on whether the PSCI firmware
resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC
or an SMC command has to be issued.
The current implementation always uses SMC. This results in crashes on
systems where the PSCI firmware is implemented in the hypervisor, e.g.
qemu-arm64_defconfig.
The logic to decide which call is needed based on the device tree is
already implemented in the PSCI firmware driver. During the EFI runtime
the device driver model is not available. But we can minimize code
duplication by merging the EFI runtime reset and poweroff code with
the PSCI firmware driver.
As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff
and reset_misc routines let's move them into the same code module.
