Yatharth Kochar	f3b4914be3	AArch32: Add generic changes in BL1 This patch adds generic changes in BL1 to support AArch32 state. New AArch32 specific assembly/C files are introduced and some files are moved to AArch32/64 specific folders. BL1 for AArch64 is refactored but functionally identical. BL1 executes in Secure Monitor mode in AArch32 state. NOTE: BL1 in AArch32 state ONLY handles BL1_RUN_IMAGE SMC. Change-Id: I6e2296374c7efbf3cf2aa1a0ce8de0732d8c98a5	2016-09-21 16:27:27 +01:00
Soby Mathew	e33b78a658	AArch32: Add support in TF libraries This patch adds AArch32 support to cpu ops, context management, per-cpu data and spinlock libraries. The `entrypoint_info` structure is modified to add support for AArch32 register arguments. The CPU operations for AEM generic cpu in AArch32 mode is also added.

Soby Mathew	532ed61838	Introduce `el3_runtime` and `PSCI` libraries This patch moves the PSCI services and BL31 frameworks like context management and per-cpu data into new library components `PSCI` and `el3_runtime` respectively. This enables PSCI to be built independently from BL31. A new `psci_lib.mk` makefile is introduced which adds the relevant PSCI library sources and gets included by `bl31.mk`. Other changes which are done as part of this patch are: * The runtime services framework is now moved to the `common/` folder to enable reuse. * The `asm_macros.S` and `assert_macros.S` helpers are moved to architecture specific folder. * The `plat_psci_common.c` is moved from the `plat/common/aarch64/` folder to `plat/common` folder. The original file location now has a stub which just includes the file from new location to maintain platform compatibility. Most of the changes wouldn't affect platform builds as they just involve changes to the generic bl1.mk and bl31.mk makefiles. NOTE: THE `plat_psci_common.c` FILE HAS MOVED LOCATION AND THE STUB FILE AT THE ORIGINAL LOCATION IS NOW DEPRECATED. PLATFORMS SHOULD MODIFY THEIR MAKEFILES TO INCLUDE THE FILE FROM THE NEW LOCATION.

AArch32: Add generic changes in BL1

This patch adds generic changes in BL1 to support AArch32 state.
New AArch32 specific assembly/C files are introduced and
some files are moved to AArch32/64 specific folders.
BL1 for AArch64 is refactored but functionally identical.
BL1 executes in Secure Monitor mode in AArch32 state.

NOTE: BL1 in AArch32 state ONLY handles BL1_RUN_IMAGE SMC.

AArch32: Add support in TF libraries

This patch adds AArch32 support to cpu ops, context management,
per-cpu data and spinlock libraries. The `entrypoint_info`
structure is modified to add support for AArch32 register
arguments. The CPU operations for AEM generic cpu in AArch32
mode is also added.

Introduce `el3_runtime` and `PSCI` libraries

This patch moves the PSCI services and BL31 frameworks like context
management and per-cpu data into new library components `PSCI` and
`el3_runtime` respectively. This enables PSCI to be built independently from
BL31. A new `psci_lib.mk` makefile is introduced which adds the relevant
PSCI library sources and gets included by `bl31.mk`. Other changes which
are done as part of this patch are:

* The runtime services framework is now moved to the `common/` folder to
  enable reuse.
* The `asm_macros.S` and `assert_macros.S` helpers are moved to architecture
  specific folder.
* The `plat_psci_common.c` is moved from the `plat/common/aarch64/` folder
  to `plat/common` folder. The original file location now has a stub which
  just includes the file from new location to maintain platform compatibility.

Most of the changes wouldn't affect platform builds as they just involve
changes to the generic bl1.mk and bl31.mk makefiles.

NOTE: THE `plat_psci_common.c` FILE HAS MOVED LOCATION AND THE STUB FILE AT
THE ORIGINAL LOCATION IS NOW DEPRECATED. PLATFORMS SHOULD MODIFY THEIR
MAKEFILES TO INCLUDE THE FILE FROM THE NEW LOCATION.
