armv8: make SPL exception vectors optional

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.

armv8: Reduce exception handling code

The arm64 exception handling code is quite big, mostly due to

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

6 years agobinman: Rename 'position' to 'offset'
Simon Glass [Wed, 1 Aug 2018 21:22:37 +0000 (15:22 -0600)]
binman: Rename 'position' to 'offset'

After some thought, I believe there is an unfortunate naming flaw in
binman. Entries have a position and size, but now that we support
hierarchical sections it is unclear whether a position should be an
absolute position within the image, or a relative position within its
parent section.

At present 'position' actually means the relative position. This indicates
a need for an 'image position' for code that wants to find the location of
an entry without having to do calculations back through parents to
discover this image position.

A better name for the current 'position' or 'pos' is 'offset'. It is not
always an absolute position, but it is always an offset from its parent
offset.

It is unfortunate to rename this concept now, 18 months after binman was
introduced. However I believe it is the right thing to do. The impact is
mostly limited to binman itself and a few changes to in-tree users to
binman:

   tegra
   sunxi
   x86

The change makes old binman definitions (e.g. downstream or out-of-tree)
incompatible if they use the 'pos = <...>' property. Later work will
adjust binman to generate an error when it is used.

tpm: allow TPM v1 and v2 to be compiled at the same time

will allow to compile test both stacks with the same sandbox defconfig.

As we cannot define two 'tpm' commands at the same time, the command for
TPM v1 is still called 'tpm' and the one for TPM v2 'tpm2'. While this
is the exact command name that must be written into eg. test files, any
user already using the TPM v2 stack can continue to do so by just writing
'tpm' because as long as TPM v1 support is not compiled, U-Boot prompt
will search for the closest command named after 'tpm'.

The command set can also be changed at runtime (not supported yet, but
ready to be), but as one can compile only either one stack or the other,
there is still one spot in the code where conditionals are used: to
retrieve the v1 or v2 command set.

ARM: tegra: implement RAM repair

RAM repair has a few pre-requisites:
1) PMIC power supply (rail) enabled.
2) PMC CRAIL power partition powered.
3) Fuse clock active (it's the default).
4) PLLP reshift branch enabled (it's the default, when PLLP is active).

RAM repair also only need run whenever specific partitions are powered
(main SoC and CCPLEX respectively); RAM repair does not need to be
triggered when any other partition changes state.

start_cpu() needs to be re-ordered slightly to match these requirements.
Note that C0NC and CE0 aren't required for RAM repair to
operate, but they also do no harm, so the entire of powerup_cpus() is
moved rather than splitting it up. The call to remove_cpu_resets() is
moved last to ensure that all other actions complete before releasing
reset; since the PMC power partitions are now enabled early, releasing
reset is what causes the CPUs to start executing code, and RAM repair must
complete before the CPU boots.

Note that this commit is the result of squashing a numbmer of commits
in NVIDIA's downstream L4T branch, hence the multiple signoffs below.
