Antonio Nino Diaz [Thu, 14 Sep 2017 14:57:44 +0000 (15:57 +0100)]
Fix type of `unsigned long` constants

The type `unsigned long` is 32 bit wide in AArch32, but 64 bit wide in
AArch64. This is inconsistent and that's why we avoid using it as per
the Coding Guidelines. This patch changes all `UL` occurrences to `U`
or `ULL` depending on the context so that the size of the constant is
clear.

This problem affected the macro `BIT(nr)`. As long as this macro is used
to fill fields of registers, that's not a problem, since all registers
are 32 bit wide in AArch32 and 64 bit wide in AArch64. However, if the
macro is used to fill the fields of a 64-bit integer, it won't be able
to set the upper 32 bits in AArch32.

By changing the type of this macro to `unsigned long long` the behaviour
is always the same regardless of the architecture, as this type is
64-bit wide in both cases.

Some Tegra platform files have been modified by this patch.

juno: Fix bug in plat_get_my_entrypoint

plat_get_my_entrypoint was branching to juno_do_reset_to_aarch_32_state,
which is not supposed to return, and in case of returning it implemented
an infinite loop. The problem was that plat_get_my_entrypoint was using
"b" instead of "bl", so juno_do_reset_to_aarch_32_state was returning to
the caller of plat_get_my_entrypoint instead of stop the system with a
panic.

To avoid this problem juno_do_reset_to_aarch_32_state was modified to
call directly to plat_panic_handler if it tries to return.

Currently, the "func" macro does not specify ".align" directive
by default.  It causes unaligned instruction under some circumstances.

[ How to reproduce the problem ]

For example, use GCC 5.3 downloaded from Linaro:

7 years agoplat/arm: Fix ARM_INSTANTIATE_LOCK syntax anomaly
Jeenu Viswambharan [Wed, 23 Aug 2017 13:12:59 +0000 (14:12 +0100)]
plat/arm: Fix ARM_INSTANTIATE_LOCK syntax anomaly

The current definition of ARM_INSTANTIATE_LOCK macro includes a
semicolon, which means it's omitted where it's used. This is anomalous
for a C statement in global scope.

Fix this by removing semicolon from the definition; and where it's a
NOP, declare a file-scoped variable explicitly tagged as unused to avoid
compiler warning.

No functional changes.
