Sughosh Ganu <sughosh.ganu@linaro.org> says:
The patch series contains some fixes and improvements in the lmb
code, along with addition of corresponding test cases for the changes
made.
The lmb_reserve() function currently does not check if the requested
reservation would overlap with existing reserved regions. While some
scenarios are being handled, some corner cases still exist. These are
being handled by patch 1, along with adding test cases for these
scenarios.
Patch 2 is handling the case of reserving a new region of memory, but
that region overlaps with an existing region. The current code only
handles one particular scenario, but prints a message for the other
scenario of an encompassing overlap and returns back. The patch
handles the encompassing overlap.
Patch 3 is an improvement whereby we allow coalescing a newly reserved
region with an existing region. The current code exits this check
prematurely.
Patch 4 is removing a now superfluous check for overlapping regions
with flag other than LMB_NONE. This now gets handled at an earlier
point in lmb_reserve().
Patch 5 is clubbing the functionality to check if two regions are
adjacent, or overlap, allowing some code re-use.
Patch 6 is optimising the lmb_alloc() function by having it call
_lmb_alloc_base() directly.

mach-snapdragon: handle platforms without PSCI support
Most MSM8916 devices shipped without PSCI support. The history is quite
nuanced (a good overview can be found in [1]), but the end result is
that the upstream DTs for this SoC pretend that PSCI exists, and it's
expected that the bootloader handles the case where it doesn't. This is
codified by the de-facto bootloader for MSM8916 devices, lk2nd [2].
So we handle it here by deleting the /psci node if we detect the absence
of PSCI. We need to do this early to ensure sysreset works correctly,
since the PSCI firmware driver is PRE_RELOC and binds the PSCI sysreset
driver.
Additionally, show_psci_version is updated to check that PSCI exists.
Currently this banner outputs "PSCI: 65535.65535" on devices without

efi_loader: Move .dynamic out of .text in EFI
EFI applications need to be relocatable. Ordinarily, this is achieved
through a PE-format .reloc section, but since that requires toolchain
tricks to achieve, U-Boot's EFI applications instead embed ELF-flavored
relocation information and use it for self-relocation; thus, the
.dynamic section needs to be preserved.
Before this patch, it was tacked on to the end of .text, but this was
not proper: A .text section is SHT_PROGBITS, while the .dynamic section
is SHT_DYNAMIC. Attempting to combine them like this creates a section
type mismatch. While GNU ld doesn't seem to complain, LLVM's lld
considers this a fatal linking error.
This patch moves .dynamic out to its own section, so that the output ELF
has the correct types. (They're all mashed together when converting to
binary anyway, so this patch causes no change in the final .efi output.)

format, and the aforementioned PE header correctly points to _start, the
ENTRY(_start) directive could easily be removed to silence this warning.

intermediary ELF may appreciate having correct entry-point information,
this patch instead promotes the _start labels to global symbols,

handoff structure used by Renesas TFA fork in fixed location in DRAM and
indicates the TFA has been loaded.
The custom armv8_switch_to_el2_prep() handling tests whether the TFA BL31

so, jumps to TFA BL31 which switches from EL3 to EL2 and then returns to
U-Boot just past bl in armv8_switch_to_el2() to finish starting the Linux
kernel.
The jump to Linux through TFA works in such a way that the custom
armv8_switch_to_el2_prep() handler configures the custom handoff structure
such that the target jump address of the TFA BL31 on exit is set to the
armv8_switch_to_el2() + 4, which is just past the bl, and just before the
U-Boot code which implements the Linux kernel boot from either EL. The
registers passed through the TFA BL31 are all the registers passed into
armv8_switch_to_el2_prep() to assure maximum compatibility with all the
boot modes. The armv8_switch_to_el2_prep() handler jumps to the TFA BL31,
which does its setup, drops EL from EL3 to EL2 and finally jumps to the
armv8_switch_to_el2() + 4 entry point, which then allows U-Boot to boot
