ARM Architecture reference manual clearly states that PE pipeline
should be flushed after changes to some system registers. Refer to
paragraph "B2.3.5 Memory Barriers" at page B2-92 of "Arm Architecture
Reference Manual ARMv8 for ARMv8-A Architecture Profile" (ARM DDI
0487B.a).
Failing to issue instruction synchronization barrier can lead to
spurious errors, like synchronous exception when accessing FPU
registers. This is very prominent on CPUs with long instruction
pipeline, like ARM Cortex A72.
ram: stm32mp1: add size and addr parameter to test all
Add size and addr parameter to test "All" to override the default
value (4kB and STM32_DDR_BASE) used in tests with these optional
parameters: [size] or [addr].
When other optional parameters are present before [addr],
they are replaced by default value:
- [loop] = "1"
- [pattern] = "-" (new: force default pattern)
ram: stm32mp1: use the DDR size by default in the test addressBus
The test 4 = "AddressBus [size] [addr]" without parameter
detects alias for any address bit only when:
- size = real size of DDR
- addr = start of DDR = 0xC0000000
These value must be the default value when parameters are absent.
This patch sets bufsize to STM32_DDR_SIZE and get_bufsize() selects
the correct value for bufsize when this parameter is absent =
full size of the DDDR
On EV1 board :
DDR> test 4
running at 0xC0000000 length 0x40000000
On DK2 board
DDR> test 4
running at 0xC0000000 length 0x20000000
ram: stm32mp1: protect minimum value in get_bufsize
Add protection on minimum value for result of get_bufsize
and check the alignment of buffer size: only multiple min_size
is allowed; only 4 bytes alignment was checked previously
(value & 0x3).
For example the "Random" test raises an issue when size is not 8 bytes
aligned because address for buffer = address + size / 2 is not word
aligned.
This patch avoid test error for unsupported size value.
Use the define ENV_IS_IN_DEVICE to test if one the
CONFIG_ENV_IS_IN_... is defined and correct the detection of
persistent storage support in the command "env info"
if CONFIG_ENV_IS_NOWHERE is activated.
Since commit 60d5ed2593c9 ("env: allow ENV_IS_NOWHERE with

enough; see also commit 953db29a1e9c6 ("env: enable saveenv

common/board_f: Respect original FDT size while relocating
While relocating FDT we reserve some memory for the new FDT and

Fix this by copying exact FDT size bytes, not the reserved size.
Radxa dalang carrier boards are used to mount vmarc SoM's
of rk3399pro and rk3288 to make complete SBC.
Among these combinations, card detection gpio, max-frequency
properties are used with rk3399pro SoM but not required for
rk3288 SoM based on the hardware schematics.
So, let's move these sdmmc specific properties on associate
vmarc dtsi to make common use of dalang carrier device tree file.
SPL_ATF_NO_PLATFORM_PARAM is selected by default for RK3399 configs, to
guard against issues when used with TF-A versions that perform
insufficient validation on the platform parameter. However, since commit 8109f738ffa7 "rockchip: increase FDT buffer size" in TF-A, passing a
device tree as platform parameter no longer causes problems for upstream
TF-A for RK3399.
Since SPL_ATF_NO_PLATFORM_PARAM doesn't need to be selected when using
upstream TF-A, change the Kconfig option from select to imply. It'll
still default to being selected but can be deselected by a user if they
know they will be using a compatible version of TF-A.

good job at deciding when to, or not to, inline code and there are no
run-time requirements in Linux anymore.
There is one downside to this, which is final binary size. On average
