2022-12-01fix: remove old-style declarationsBoyan Karatotev
TF-A wants to eventually enable -Wold-style-definition globally. Convert the rare few instances where this is still the case. Signed-off-by: Boyan Karatotev <boyan.karatotev@arm.com> Change-Id: I9c450fc875cf097e6de2ed577ea3b085821c9f5e
2022-05-07feat(imx8/imx8m): switch to xlat_tables_v2Ji Luo
spd trusty requires memory dynamic mapping feature to be enabled, so we have to use xlat table library v2 instead of v1. Signed-off-by: Ji Luo <ji.luo@nxp.com> Signed-off-by: Jacky Bai <ping.bai@nxp.com> Change-Id: I2813af9c7878b1fc2a59e27619c5b643af6a1e91
2021-11-08fix: libc: use long for 64-bit types on aarch64Scott Branden
Use long instead of long long on aarch64 for 64_t stdint types. Introduce inttypes.h to properly support printf format specifiers for fixed width types for such change. Change-Id: I0bca594687a996fde0a9702d7a383055b99f10a1 Signed-off-by: Scott Branden <scott.branden@broadcom.com>
2020-03-16plat: imx: imx8qm: provide debug uart num as build paramIgor Opaniuk
This removes hardcoded iomux/clk/addr configuration for debug uart, provides possibility (as a workaround, till that information isn't provided via DT) to set this configuration during compile time via IMX_DEBUG_UART build flag. Usage: $ make PLAT=imx8qm IMX_DEBUG_UART=1 bl31 Signed-off-by: Igor Opaniuk <igor.opaniuk@gmail.com> Change-Id: Ib5f5dd81ba0c8ad2b2dc5647ec75629072f511c5
2020-02-25imx: Use generic console_t data structureAndre Przywara
Since now the generic console_t structure holds the UART base address as well, let's use that generic location and drop the UART driver specific data structure at all. Change-Id: I058f793e4024fa7291e432f5be374a77faf16f36 Signed-off-by: Andre Przywara <andre.przywara@arm.com>
2020-01-28Enable -Wredundant-decls warning checkMadhukar Pappireddy
This flag warns if anything is declared more than once in the same scope, even in cases where multiple declaration is valid and changes nothing. Consequently, this patch also fixes the issues reported by this flag. Consider the following two lines of code from two different source files(bl_common.h and bl31_plat_setup.c): IMPORT_SYM(uintptr_t, __RO_START__, BL_CODE_BASE); IMPORT_SYM(unsigned long, __RO_START__, BL2_RO_BASE); The IMPORT_SYM macro which actually imports a linker symbol as a C expression. The macro defines the __RO_START__ as an extern variable twice, one for each instance. __RO_START__ symbol is defined by the linker script to mark the start of the Read-Only area of the memory map. Essentially, the platform code redefines the linker symbol with a different (relevant) name rather than using the standard symbol. A simple solution to fix this issue in the platform code for redundant declarations warning is to remove the second IMPORT_SYM and replace it with following assignment static const unsigned long BL2_RO_BASE = BL_CODE_BASE; Change-Id: If4835d1ee462d52b75e5afd2a59b64828707c5aa Signed-off-by: Madhukar Pappireddy <madhukar.pappireddy@arm.com>
2019-01-29imx: power optimization for i.mx8qmAnson Huang
Current implementation of i.MX8QM power management related features does NOT optimize power number, all system resources like CCI, DDR, and A cluster etc. are kept in STBY mode (powered ON) when system suspend or CPU hotplug. To lower the power number, OFF mode should be adopted for those system resources whenever they can be OFF, A cluster will be OFF if the CPUs in the cluster are all off line, DDR/MU/DB can be OFF if system suspend, IRQ steer can be OFF if the wakeup source is belonged to system controller partition, so wakeup source runtime check is used to determine if IRQ steer can be OFF before system suspend. If resources are powered off for suspend, they should be restored properly after system resume. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
2019-01-04Sanitise includes across codebaseAntonio Nino Diaz
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.

- Migrate to new GIC interfaces. - Migrate to bl31_early_platform_setup2(). - Remove references to removed build options. Change-Id: Ia7c63f75325ea4b41e32a9de3f01b0007d0ae210 Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
