When PIE is enabled in start.S, u-boot/-spl use __rel_dyn_start
and _rel_dyn_end symbol to be loaded to and executed at a
different address than it was linked at.
u-boot-spl.lds is used in SPL build, but relocation information
section(.rela*) were discarded.
In line number 80 in arch/arm/cpu/armv8/u-boot-spl.lds
/DISCARD/ : { *(.rela*) }
If PIE enabled in SPL, __rel_dyn_start which is defined as
.rel_dyn_start in sections.c will be apended to the end of
.bss section.
In our ASPEED case, size of .bss section would let .rel_dyn_start
without 8-byte alignment, leading to alignment fault when
executing ldp instuction in pie_fix_loop.

Now all linker symbols are declared as type char[]. Though we can
reference the address via both the array name 'var' and its address
'&var'. It's better to unify them to avoid confusing developers.
This patch converts all '&var' linker symbol refrences to the most
commonly used format 'var'.

It is not a parse error to have a default value of "0" for a "hex" type
entry, instead of "0x0". However, "0" and "0x0" are not treated the
same even by the tools themselves. Correct this by changing the default
value from "0" to "0x0" for all hex type questions that had the
incorrect default. Fix one instance (in two configs) of a default of "0"
being used on a hex question to be "0x0". Remove the cases where a
defconfig had set a value of "0x0" to be used as the default had been
"0".

Allow individual Layerscape boards to opt-out of fsl_setenv_bootcmd
by declaring the original function as weak.
fsl_setenv_bootcmd is used to change the bootcmd based on the
TF-A boot source (e.g QSPI vs SD/MMC) for reasons including
secure boot / integrity measurements and DPAA2 configuration loading.
See previous discussion at [1].
On the Ten64 board, our bootcmd is the same across
all TF-A boot sources so we don't want this behaviour.

This commit provides function, which when debugging
output is enabled dumps the IMX28 PMU registers.
Signed-off-by: Lukasz Majewski <[email protected]>
|
|
The IMX28 PMU (Power Management Unit) has a dedicated Linear Regulator
to produce (by default) 4.2V output - available outside the chip as
VDD_4P2.
When system is supposed to not use VDD5V as a main power source - instead
the DCDC_BATT is used; it is safe to disable this regulator.
As the in-PMU DCDC switching regulator (from which DCDC_VDDA, DCDC_VDDIO
and DCDC_VDDD are generated) can be driven from DCDC_BATT or output
of this 4P2 regulator - by disabling the latter the use of the DCDC_BATT
is forced.
To be more specific - according to NXP's AN4199 the DCDC_BATT source is
preferred (over VDD5V), as more efficient and stable source for
industrial applications.

This new Kconfig option allows disabling the in-PMU battery charging
block. This may be required when DCDC_BAT source is powered not from
battery, but from already regulated, good quality source.

This option sets the current limit for 5V source to zero, so all
the PMU outputs are primarily powered from battery source (DCDC_BAT).
This option may be set on systems, where the 5V is NOT supposed to be
in any scenario powering the system - for example on systems where
DCDC_BAT is connected to fixed and regulated 4.2V source (so the
"battery" is not present).

In the add_map() function, for each level it populates, it iterates from
the root of the PT tree, making it ineficient if a mapping needs to occur
past level 1.
Instead, replace it with a recursive (and much simpler) algorithm
that keeps the complexity as low as possible. With this, mapping
512GB at level 2 goes from several seconds down to not measurable
on an A55 machine.
We keep the block mappings at level 1 for now though.

Exposing set/way cache maintenance to a virtual machine is unsafe, not
least because the instructions are not permission-checked but also
because they are not broadcast between CPUs. Consequently, KVM traps and
emulates such maintenance in the host kernel using by-VA operations and
looping over the stage-2 page-tables. However, when running under
protected KVM, these instructions are not able to be emulated and will
instead result in an exception being delivered to the guest.
Introduce CONFIG_CMO_BY_VA_ONLY so that virtual platforms can select
this option and perform by-VA cache maintenance instead of using the
set/way instructions.
