binman: Respect pad-before property of section subentries
Other relevant properties (pad-after, offset, size, align, align-size,
align-end) already work since Pack() sets correct ranges for subentries'

align the data within this range to match the pad-before property.

cmd: mem: fix range of bitflip test
The bitflip test uses two equal sized memory buffers. This is achieved
by splitting the range of memory into two pieces. The address of the
second buffer, as well as the length of each buffer, were not correctly
calculated. This caused bitflip test to access beyond the end of range.
This patch fixes the pointer arithmetic problem.
A second problem arises because u-boot "mtest" command expects the
ending address to be inclusive. When computing (end - start) this
results in missing 1 byte of the requested length. The bitflip test
expects a count rather than an "ending" address. Thus it fails to test
the last word of the requested range. Fixed by using (end - start + 1).
Added Kconfig option to optionally disable the bitflip test, since it
does add significantly to the time taken for "mtest".

two banks). The TCMs of both Cores are combined in LockStep-mode
to provide a larger 128 KB of memory.
Add the DT node for the MCU domain R5F cluster/subsystem, the two
R5F cores are added as child nodes to the main cluster/subsystem node.
The cluster is configured to run in LockStep mode by default, with
the ATCMs enabled to allow the R5 cores to execute code from DDR with
boot-strapping code from ATCM. The inter-processor communication
between the main A72 cores and these processors is achieved through
shared memory and Mailboxes.

armv8: K3: j7200: Add custom MMU support
The A72 U-Boot code can load and boot a number of the available
R5FSS Cores on the J7200 SoC. Change the memory attributes for the
DDR regions used by the remote processors so that the cores can see
and execute the proper code.
The J7200 SoC has less number of remote processors compared to J721E,
so use less memory for the remote processors. So, a separate table
based on the current J721E table is added for J7200 SoCs, and selected
using the appropriate Kconfig CONFIG_TARGET_J7200_A72_EVM symbol.

remoteproc: k3-r5: Add support for J7200 R5Fs
The K3 J7200 SoC family has a revised R5F sub-system and contains a
subset of the R5F clusters present on J721E SoCs. The integration of
these clusters is very much similar to J721E SoCs otherwise.
The revised IP has the following two new features:
1. TCMs are auto-initialized during module power-up, and the behavior
is programmable through a MMR bit controlled by System Firmware.
2. The LockStep-mode allows the Core1 TCMs to be combined with the
Core0 TCMs effectively doubling the amount of TCMs available.
The LockStep-mode on previous SoCs could only use the Core0 TCMs.
This combined TCMs appear contiguous at the respective Core0 TCM
addresses.
Add the support to these clusters in the K3 R5F remoteproc driver
using J7200 specific compatibles and revised logic accounting for
the above IP features/differences.

dt-bindings: remoteproc: k3-r5f: Update bindings for J7200 SoCs
The K3 J7200 SoCs have two dual-core Arm R5F clusters/subsystems, with
2 R5F cores each, one in each of the MCU and MAIN voltage domains.
These clusters are a revised version compared to those present on
J721E SoCs. Update the K3 R5F remoteproc bindings with the compatible
info relevant to these R5F clusters/subsystems on K3 J7200 SoCs.

env: ti: j721e-evm: Limit scope of rproc env variables used by R5 SPL
The commit 316c927135d6 ("include: configs: j721e_evm: Add env variables
for mcu_r5fss0_core0 & main_r5fss0_core0") added four different new env
variables 'addr_mainr5f0_0load', 'name_mainr5f0_0fw', 'addr_mcur5f0_0load'
and 'name_mcur5f0_0fw' to the generic environment, but these are only
needed and used in R5 SPL for early-booting the MCU R5FSS0 and Main
R5FSS0 Core0 on J721E SoCs.
These are not really needed for A72 U-Boot, so limit the scope of
these variables only to R5 SPL. While at this, also fix the loadaddr
variable values to include the hex prefix like with other such env
variables.

configs: j721e_evm: Add Main R5FSS1 Core1 to default rproc boot list
The default rproc list currently used by A72 U-Boot to boot various
remote processors include the Main R5FSS0 (Split-mode) Core1, Main
R5FSS1 (LockStep mode) Core0 and the three DSPs. The Main R5FSS1 cluster
is configured for Split mode by default in the dts now, so add the
Main R5FSS1 Core1 (rproc #5) to the default rproc boot list. This
core is now booted after the Main R5FSS1 Core0 and before the DSPs.
The order of the rprocs to boot can always be changed at runtime if
desired by overwriting the 'rproc_fw_binaries' environment variable
at U-boot prompt. Note that the R5FSS Core1 cannot be booted before
its associated Core0.

board: ti: j721e: Add support for HyperFlash detection
On J7200 SoC OSPI and HypeFlash are muxed at HW level and only one of
them can be used at any time. J7200 EVM has both HyperFlash and OSPI
flash on board. There is a user switch (SW3.1) that can be toggled to
select OSPI flash vs HyperFlash.
Read the state of this switch via wkup_gpio0_6 line and fixup the DT
nodes to select OSPI vs HyperFlash
HBMC controller on TI K3 SoC provides MMIO access to HyperFlash similar
to legacy Parallel CFI NOR flashes. Therefore alias HyperFlash bootmode
to NOR boot to enable SPL to load next stage using NOR boot flow.
