      rockchip: Implement a panic handler that will reboot the system · a33e763c
      Julius Werner authored
      
      
      The current Rockchip platform code retains the "common" default panic
      handler which simply hangs the system (until the watchdog kicks in, if
      enabled). This is usually not a great user experience.
      
      This patch implements a Rockchip-specific panic handler that calls the
      platform's reboot implementation to reset the system.

      Add new alignment parameter to func assembler macro · 64726e6d
      Julius Werner authored
      
      
      Assembler programmers are used to being able to define functions with a
      specific aligment with a pattern like this:
      
          .align X
        myfunction:
      
      However, this pattern is subtly broken when instead of a direct label
      like 'myfunction:', you use the 'func myfunction' macro that's standard
      in Trusted Firmware. Since the func macro declares a new section for the
      function, the .align directive written above it actually applies to the
      *previous* section in the assembly file, and the function it was
      supposed to apply to is linked with default alignment.
      
      An extreme case can be seen in Rockchip's plat_helpers.S which contains
      this code:
      
        [...]
        endfunc plat_crash_console_putc
      
        .align 16
        func platform_cpu_warmboot
        [...]
      
      This assembles into the following plat_helpers.o:
      
        Sections:
        Idx Name                             Size  [...]  Algn
         9 .text.plat_crash_console_putc 00010000  [...]  2**16
        10 .text.platform_cpu_warmboot   00000080  [...]  2**3
      
      As can be seen, the *previous* function actually got the alignment
      constraint, and it is also 64KB big even though it contains only two
      instructions, because the .align directive at the end of its section
      forces the assembler to insert a giant sled of NOPs. The function we
      actually wanted to align has the default constraint. This code only
      works at all because the linker just happens to put the two functions
      right behind each other when linking the final image, and since the end
      of plat_crash_console_putc is aligned the start of platform_cpu_warmboot
      will also be. But it still wastes almost 64KB of image space
      unnecessarily, and it will break under certain circumstances (e.g. if
      the plat_crash_console_putc function becomes unused and its section gets
      garbage-collected out).
      
      There's no real way to fix this with the existing func macro. Code like
      
       func myfunc
       .align X
      
      happens to do the right thing, but is still not really correct code
      (because the function label is inserted before the .align directive, so
      the assembler is technically allowed to insert padding at the beginning
      of the function which would then get executed as instructions if the
      function was called). Therefore, this patch adds a new parameter with a
      default value to the func macro that allows overriding its alignment.
      
      Also fix up all existing instances of this dangerous antipattern.

      Introduce utils.h header file · ed81f3eb
      Sandrine Bailleux authored
      This patch introduces a new header file: include/lib/utils.h.
      Its purpose is to provide generic macros and helper functions that
      are independent of any BL image, architecture, platform and even
      not specific to Trusted Firmware.
      
      For now, it contains only 2 macros: ARRAY_SIZE() and
      IS_POWER_OF_TWO(). These were previously defined in bl_common.h and
      xlat_tables.c respectively.
      
      bl_common.h includes utils.h to retain compatibility for platforms
      that relied on bl_common.h for the ARRAY_SIZE() macro. Upstream
      platform ports that use this macro have been updated to include
      utils.h.

      Move `plat_get_syscnt_freq()` to arm_common.c · c073fda1
      Yatharth Kochar authored
      This patch moves the definition for `plat_get_syscnt_freq()`
      from arm_bl31_setup.c to arm_common.c. This could be useful
      in case a delay timer needs to be installed based on the
      generic timer in other BLs.
      This patch also modifies the return type for this function
      from `uint64_t` to `unsigned long long` within ARM and other
      platform files.

      This patch adds to support the RK3368 and RK3399 SoCs.
      
      RK3368/RK3399 is one of the Rockchip family SoCs, which is an
      multi-cores ARM SoCs.
      
      This patch adds support to boot the Trusted Firmware on RK3368/RK3399
      SoCs, and adds support to boot secondary CPUs, enter/exit core
      power states for all CPUs in the slow/fast clusters.
      
      This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs)
      * Support arm gicv2 & gicv3.
      * Boot up multi-cores CPU.
      * Add generic CPU helper functions.
      * Support suspend/resume.
      * Add system_off & system_reset implementation.
      * Add delay timer platform implementation.
      * Support the new porting interface for the PSCI implementation.
