Fix Coverity #343008, Side affect in assertion

2019-08-06T12:06:03Z

This patch simply splits off the increment of next_xlat into a separate statement to ensure consistent behaviour if the assert was to ever be removed. Change-Id: I827f601ccea55f4da9442048419c9b8cc0c5d22e Signed-off-by: Justin Chadwell

Update base code to not rely on undefined overflow behaviour

2019-07-12T08:12:19Z

This consists of ensuring that the left operand of each shift is unsigned when the operation might overflow into the sign bit. Change-Id: Iddd6f38139a4c6e500468b4fc48d04e0939f574e Signed-off-by: Justin Chadwell

ARMv7: support non-LPAE mapping (not xlat_v2)

2019-02-19T17:07:48Z

Support 32bit descriptor MMU table. This is required by ARMv7 architectures that do not support the Large Page Address Extensions. nonlpae_tables.c source file is dumped from the OP-TEE project: core_mmu_armv7.c and related header files.

lib/xlat_tables: Add support for ARMv8.4-TTST

2019-01-30T11:17:38Z

ARMv8.4-TTST (Small Translation tables) relaxes the lower limit on the size of translation tables by increasing the maximum permitted value of the T1SZ and T0SZ fields in TCR_EL1, TCR_EL2, TCR_EL3, VTCR_EL2 and VSTCR_EL2. This feature is supported in AArch64 state only. This patch adds support for this feature to both versions of the translation tables library. It also removes the static build time checks for virtual address space size checks to runtime assertions. Change-Id: I4e8cebc197ec1c2092dc7d307486616786e6c093 Signed-off-by: Sathees Balya

Sanitise includes across codebase

2019-01-04T10:43:17Z

Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

xlat: Remove deprecated interfaces

xlat v2: Support the EL2 translation regime

2018-08-10T12:47:11Z

The translation library is useful elsewhere. Even though this repository doesn't exercise the EL2 support of the library, it is better to have it here as well to make it easier to maintain. enable_mmu_secure() and enable_mmu_direct() have been deprecated. The functions are still present, but they are behind ERROR_DEPRECATED and they call the new functions enable_mmu_svc_mon() and enable_mmu_direct_svc_mon().

xlat: Fix MISRA defects

2018-07-30T08:30:15Z

Fix defects of MISRA C-2012 rules 8.13, 10.1, 10.3, 10.4, 10.8, 11.6, 14.4, 15.7, 17.8, 20.10, 20.12, 21.1 and Directive 4.9. Change-Id: I7ff61e71733908596dbafe2e99d99b4fce9765bd Signed-off-by: Antonio Nino Diaz

xlat v1: Provide direct MMU-enabling stubs

2018-06-27T10:31:30Z

An earlier patch split MMU-enabling function for translation library v2. Although we don't intend to introduce the exact same functionality for xlat v1, this patch introduces stubs for directly enabling MMU to maintain API-compatibility.

ARMv7 may not support large page addressing

2017-11-08T12:53:47Z

ARCH_SUPPORTS_LARGE_PAGE_ADDRESSING allows build environment to handle specific case when target ARMv7 core only supports 32bit MMU descriptor mode. If ARMv7 based platform does not set ARM_CORTEX_Ax=yes, platform shall define ARMV7_SUPPORTS_LARGE_PAGE_ADDRESSING to enable large page addressing support. Signed-off-by: Etienne Carriere
