The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF
images and u-boot, and does this for virtual platforms by using
semihosting. This commit extends this idea by allowing u-boot to also
use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
for a bootwrapper and produces a more realistic boot sequence with
virtual models.
Though the semihosting code is quite generic, support for armv7 in
fastmodel is less useful due to the wide range of available silicon
and the lack of a free armv7 fastmodel, so this change contains an
untested armv7 placeholder for the service trap opcode.
Please refer to doc/README.semihosting for a more detailed description
of semihosting and how it is used with the armv8 virtual platforms.

U-Boot has supported two kinds of asm-offsets.h.
One is generic for all architectures and its source is located at
./lib/asm-offsets.c.
The other is SoC specific and its source is under SoC directory.
The problem here is that only boards with SoC directory can use
the asm-offsets infrastructure.
Putting asm-offsets.c right under CPU directory does not work.
Now a new demand is coming. PowerPC folks want to use asm-offsets.
But no PowerPC boards have SoC directory.
It seems inconsistent that some boards add asm-offsets.c to SoC
directoreis and some to CPU directories.
It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib.
This commit merges asm-offsets.c under SoC directories into
arch/$(ARCH)/lib/asm-offsets.c.
By the way, I doubt the necessity of some entries in asm-offsets.c.
I am leaving refactoring to the board maintainers.

Before this commit, USE_PRIVATE_LIBGCC was defined in
arch-specific config.mk and referenced in
arch/$(ARCH)/lib/Makefile.
We are not happy about parsing config.mk again and again.
We have to keep the same behavior with a different way.
By adding "CONFIG_" prefix, this macro appears
in include/autoconf.mk, include/spl-autoconf.mk.
(And treating USE_PRIVATE_LIBGCC as CONFIG macro
is reasonable enough.)
Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
in arch/arm/cpu/arm720t/tegra*/config.mk,
whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.
It means Tegra enables PRIVATE_LIBGCC only for SPL.

# define CONFIG_USE_PRIVATE_LIBGCC

When we tell the compiler to optimize for ARMv7 (and ARMv6 for that

For the KVM and XEN hypervisors to be usable, we need to enter the
kernel in HYP mode. Now that we already are in non-secure state,
HYP mode switching is within short reach.
While doing the non-secure switch, we have to enable the HVC
instruction and setup the HYP mode HVBAR (while still secure).
The actual switch is done by dropping back from a HYP mode handler
without actually leaving HYP mode, so we introduce a new handler
routine in our new secure exception vector table.
In the assembly switching routine we save and restore the banked LR
and SP registers around the hypercall to do the actual HYP mode
switch.
The C routine first checks whether we are in HYP mode already and
also whether the virtualization extensions are available. It also
checks whether the HYP mode switch was finally successful.
The bootm command part only calls the new function after the
non-secure switch.

This option delays loading of the environment until later, so that only the
default environment will be available to U-Boot.
This can address the security risk of untrusted data being used during boot.
Any time you load untrusted data you expose yourself to a bug in the
code. The attacker gets to choose the data so can sometimes carefully
craft it to exploit a bug. We try to avoid touching user-controlled
data during a verified boot unless strictly necessary. Since the
default environment is good enough in this case (or you would just
change it), this gets around the problem by just not loading the
environment.
When CONFIG_DELAY_ENVIRONMENT is defined, it is convenient to have a
run-time way of enabling loading of the environment. Add this to the
fdt as /config/delay-environment.

So far ARM and microblaze are the only only ones that use
CONFIG_OF_CONTROL. Microblaze does not have the same init loop, and in
particular does not have the board_early_init_f() call. So a patch for
microblaze would have no meaning.

In Cortex-A15 architecture, when we run cache invalidate
the cache clean operation executes automatically.
So if there are any dirty cache lines before disabling the L2 cache
these will be synchronized with the main memory when
invalidate_dcache_all() runs in the last part of U-boot
The two functions after flush_dcache_all is using the stack. So this
data will be on the cache. After disable when invalidate is called the
data will be flushed from cache to memory. This corrupts the stack in
invalida_dcache_all. So this change is required to avoid the u-boot
hang.
So flush has to be done just before clearing CR_C bit

Move all the C runtime setup code from every start.S
in arch/arm into arch/arm/lib/crt0.S. This covers
the code sequence from setting up the initial stack
to calling into board_init_r().
Also, rewrite the C runtime setup and make functions
board_init_*() and relocate_code() behave according to
normal C semantics (no jumping across the C stack any
more, etc).
Some SPL targets had to be touched because they use
start.S explicitly or for some reason; the relevant

In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer,
clear the BSS and call board_init_r. We mark this as weak as some
platforms may need to perform additional initalization at this point.
We provide a gd that we know will be in a usable location, once the BSS
has been cleared to help with this as well. Finally, we no longer call
relocate_code so remove that from the armv7 version.
Next, both board_init_f and jump_to_image_linux are going to be

The following is the cleanup sequence in arch/arm/cpu/armv7/cpu.c
int cleanup_before_linux(void)
{
...
...
dcache_disable();
v7_outer_cache_disable();
invalidate_dcache_all();
}
1) invalidate_dcache_all call expects that all the caches has been
flushed, invalidated and there are no dirty entries prior to its
execution. In the above sequence dcache_disable() flushes, invalidates
the caches and turns off the mmu. But after it cleanups the cache
and before the mmu is disabled there is a cp_delay() function which
has STR instruction. On certain cores like the cortex-a15, cache hit
and a write can happen to a cache line even when the dcache is
disabled. So the above mentioned STR instruction creates a dirty entry
after cleaning. The mmu gets disabled after this.
2) invalidate_dcache_all invalidates the cache lines. Again on
cores like cortex-a15, invalidate instruction flushes the dirty
line as well. So some times the dirty line from sequence 1
can corrupt the memory resulting in a crash.
Fixing this by moving the get_cr() and cp_delay() calls before
cleaning up the cache, thus avoiding the dirty entry.
