By default, CONFIG_SYS_INIT_SP_BSS_OFFSET was made invisible by not
giving a prompt to it.
The only way to define it is to hard-code an extra entry in SoC/board
Kconfig, like arch/arm/mach-tegra/tegra{186,210}/Kconfig.
Add a prompt to it in order to allow defconfig files to specify the
value of CONFIG_SYS_INIT_SP_BSS_OFFSET.
With this, CONFIG_SYS_INIT_SP_BSS_OFFSET would become always visible.
So, we need a new bool option to turn it off by default.
I move the 'default 524288' to the common place. This value is not too
big, but is big enough to avoid the overwrap of DT in most platforms.
If 512KB is not a suitable choice for your platform, you can change it
from your defconfig or menuconfig etc.

Flushing L3 cache may need variable time depending upon cache line
allocation.
Coming up with a proper timeout value would be best handled by
simulations under multiple scenarios in your actual system.
>From the purely HN-F point of view, the flush would take ~15 cycles for
a clean line, and ~22 cycles for a dirty line. For the dirty line case,
there are many variables outside the HN-F that will increase the
duration per line. For example, a *DBIDResp from the SN-F/SBSX,
memory controller latency, SN-F/SBSX RetryAck responses, CCN ring
congestion, CCN ring hops, etc, etc. The worst-case timeout would
have to factor in all of these variables plus the HN-F cycles for
every line in the L3, and assuming all lines are dirty
In case if L3 is not flushed properly, system behaviour will be
erratic, so remove timeout and add loop to check status of L3 cache.
System will stuck in while loop if there is some issue in L3 cache
flushing.

There are 5 places in the code where we find:
#if !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))
and 4 places in the code where we find:
#if (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF))
In words, the construct:
!defined(CONFIG_SYS_[DI]CACHE_OFF)
means:
"is the [DI]CACHE on?"
and the construct:
defined(CONFIG_SYS_[DI]CACHE_OFF)
means:
"is the [DI]CACHE off?"
Therefore
!(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))
means:
"the opposite of 'are they both off?'"
in other words:
"are either or both on?"
and:
(!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF)
means:
"are either or both on?"
As a result, I've converted the 4 instances of '(!A || !B)' to '!(A && B)' for

On AM654 SoC(arm64) which is IO coherent and has L3 Cache, cache
maintenance operations being done to support non-coherent platforms
causes issues.
For example, here is how U-Boot prepares/handles a buffer to receive
data from a device (DMA Write). This may vary slightly depending on the
driver framework:
Start DMA to write to destination buffer
Wait for DMA to be done (dma_receive()/dma_memcpy())
Invalidate destination buffer (invalidate_dcache_range())
Read from destination buffer
The invalidate after the DMA is needed in order to read latest data from
memory that’s updated by DMA write. Also, in case random prefetch has
pulled in buffer data during the “wait for DMA” before the DMA has
written to it. This works well for non-coherent architectures.
In case of coherent architecture with L3 cache, DMA write would directly
update L3 cache contents (assuming cacheline is present in L3) without
updating the DDR memory. So invalidate after “wait for DMA” in above
sequence would discard latest data and read will cause stale data to be
fetched from DDR. Therefore invalidate after “wait for DMA” is not
always correct on coherent architecture.
Therefore, provide a Kconfig option to disable cache maintenance ops on
coherent architectures. This has added benefit of improving the
performance of DMA transfers as we no longer need to invalidate/flush
individual cache lines(especially for buffer thats several KBs in size).
In order to facilitate use of same Kconfig across different
architecture, I have added the symbol to top level arch/Kconfig file.
Patch currently disables cache maintenance ops for arm64 only.
flush_dcache_all() and invalidate_dcache_all() are exclusively used
during enabling/disabling dcache and hence are not disabled.

some dpmacs in armv8a based freescale layerscape SOCs can be

e.g. dpmac 17 and 18 in LX2160A can be configured as SGMII from
serdes bits and as RGMII via EC1_PMUX/EC2_PMUX bits
Now if a dpmac is enabled by serdes bits then it takes precedence
over EC*_PMUX bits. i.e. in LX2160A if we select serdes protocol
that configures dpmac17 as SGMII and set the EC1_PMUX as RGMII,
then the dpmac is SGMII and not RGMII.
Therefore, move the fsl_rgmii_init after fsl_serdes_init. in

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.

Even though the exception vector table is a fundamental part of the ARM
architecture, U-Boot mostly does not make real use of it, except when
crash dumping. But having it in takes up quite some space, partly due to
the architectural alignment requirement of 2KB. Since we don't take special
care of that, the compiler adds a more or less random amount of padding
space, which increases the image size quite a bit, especially for the SPL.
On a typical Allwinner build this is around 1.5KB of padding, plus 1KB
for the vector table (mostly padding space again), then some extra code
to do the actual handling. This amounts to almost 10% of the maximum image
size, which is quite a lot for a pure debugging feature.
Add a Kconfig symbol to allow the exception vector table to be left out
of the build for the SPL.
For now this is "default y" for everyone, but specific defconfigs,
platforms or .config files can opt out here at will, to mitigate the code
size pressure we see for some SPLs.
Signed-off-by: Andre Przywara <andre.przywara@arm.com>
The arm64 exception handling code is quite big, mostly due to
architectural alignment requirements. Each exception entry spans 32
instructions, which sounds generous, but is too small to fit all of the
save/branch/restore code in there. So at the moment we use only four
instructions, branching into shared save and restore routines.
To not leave the space for those remaining 28 instructions wasted, let's
split the save and restore routines and stuff them into the gaps.
This saves about 250 bytes of code, which is helpful for those tight
SPLs.

Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.
In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".
Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.
With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

NOTE: This patch in itself is NOT the final solution, this requires:
a) Implementation of v7_arch_cp15_set_acr on SoCs which may not
provide direct access to ACR register.
b) Operating Systems such as Linux to provide adequate workaround in the
right locations.
c) This workaround applies to only the boot processor. It is important
to apply workaround as necessary (context-save-restore) around low
power context loss OR additional processors as necessary in either
firmware support OR elsewhere in OS.

As recommended by Arm in [1], IBE[2] has to be enabled unconditionally
for BPIALL to be functional on Cortex-A8 processors. Provide a config
option for platforms to enable this option based on impact analysis
for products.
NOTE: This patch in itself is NOT the final solution, this requires:
a) Implementation of v7_arch_cp15_set_acr on SoCs which may not
provide direct access to ACR register.
b) Operating Systems such as Linux to provide adequate workaround in the right
locations.
c) This workaround applies to only the boot processor. It is important
to apply workaround as necessary (context-save-restore) around low
power context loss OR additional processors as necessary in either
firmware support OR elsewhere in OS.

cpu_cmd() is reading cpu number via simple_strtoul() which is always
unsigned type.
Platform code implementations are not expecting that nr can be negative
and there is not checking in the code for that too.
This patch is using u32 type for cpu number to make sure that platform
code get proper value range.

If many values differ from the defaults, overriding the full table
is simpler and more space efficient than tweaking it through
mxs_adjust_memory_params().

We currently handle the UEFI runtime reset / power off case handling via
a switch statement. Compilers (gcc in my case) may opt to handle these via
jump tables which they may conveniently put into .rodata which is not part
of the runtime section, so it will be unreachable when executed.
Fix this by just converting the switch statement into an if/else statement.
It produces smaller code that is faster and also correct because we no
longer refer .rodata from efi runtime code.

The UEFI spec mandates that unaligned memory access should be enabled if
supported by the CPU architecture.
This patch implements the function unaligned_access() to reset the aligned
access flag in the system control register (SCTLR). It is called when the
bootefi command is invoked.

This patch fills the MMU map for DDR at run time based on information read
from Device Tree or automatically detected from static configuration.
The patch is needed because for systems which has for example 1GB of memory
but MMU map is 2GB there could be spurious accesses which was seen in past
when mapping is not fitting with actual memory installed.

Mask HRESET_B after cleared the the RCW_SRC, because in the workaround
we override the RCW_SRC and if HRESET_B is issued after the override
then SoC cannot find valid RCW as the RCW_SRC was overwritten and
result in hang. So we need to mask HRESET_B in case user asserts it,
and the PORESET_B should be asserted which leads to resampling of
cfg_rcw_src pins and loading of correct RCW_SRC.
