      Tegra: spe: uninit console on a timeout · 8a47fe43
      Varun Wadekar authored
      
      
      There are chances a denial-of-service attack, if an attacker
      removes the SPE firmware from the system. The console driver
      would end up waiting for the firmware to respond indefinitely.
      The console driver must detect such scenarios and uninit the
      interface as a result.
      
      This patch adds a timeout to the interaction with the SPE
      firmware and uninits the interface if it times out.

      Tegra: spe: prepend '\r' to '\n' · 843d0aad
      Varun Wadekar authored
      
      
      This patch udpates the SPE console driver to prepend '\r' to
      '\n'. This fixes the alignment of prints seen by the host
      machines on their UART ports.
      
      Tested by collecting the logs from host PC using Cutecom

      Tegra: spe: shared console for Tegra platforms · dd20f5b3
      Varun Wadekar authored
      
      
      There are Tegra platforms which have limited UART ports and so
      all the components have to share the console. The SPE helps out
      by collecting all the logs in such cases and prints them on the
      shared UART port.
      
      This patch adds a driver to communicate with the SPE driver, which
      in turn provides the console.

      Move console drivers to AArch64 folder · 9c94d3b3
      Soby Mathew authored
      This patch moves the various assembly console drivers
      into `aarch64` architecture specific folder. Stub files,
      which include files from new location, are retained at the
      original location for platform compatibility reasons.

      Use uintptr_t as base address type in ARM driver APIs · 02462972
      Juan Castillo authored
      This patch changes the type of the base address parameter in the
      ARM device driver APIs to uintptr_t (GIC, CCI, TZC400, PL011). The
      uintptr_t type allows coverage of the whole memory space and to
      perform arithmetic operations on the addresses. ARM platform code
      has also been updated to use uintptr_t as GIC base address in the
      configuration.
      
      Fixes ARM-software/tf-issues#214

      Separate out common console functionality · d3b638cb
      Dan Handley authored
      Separate out the common console functionality in
      `drivers/arm/pl011/pl011_console.S` into a new source file
      `drivers/console/console.S`. The former includes the latter to
      provide backwards compatibility for platform make files.
      
      Also add a skeleton console implementation for platforms that do not
      want to use PL011.

      Add support to indicate size and end of assembly functions · 8b779620
      Kévin Petit authored
      
      
      In order for the symbol table in the ELF file to contain the size of
      functions written in assembly, it is necessary to report it to the
      assembler using the .size directive.
      
      To fulfil the above requirements, this patch introduces an 'endfunc'
      macro which contains the .endfunc and .size directives. It also adds
      a .func directive to the 'func' assembler macro.
      
      The .func/.endfunc have been used so the assembler can fail if
      endfunc is omitted.
      
      Fixes ARM-Software/tf-issues#295

      Parametrize baudrate and UART clock during console_init() · 462c8350
      Soby Mathew authored
      This patch adds baud rate and UART clock frequency as parameters
      to the pl011 driver api console_init(). This allows each platform
      to specify UART clock and baud rate according to their specific
      hardware implementation.

      Introduce asm console functions in TF · fce5f750
      Soby Mathew authored
      This patch replaces the pl011 console family of functions
      with their equivalents defined in assembly. The baud rate is
      defined by the PL011_BAUDRATE macro and IBRD and FBRD values
      for pl011 are computed statically. This patch will enable
      us to invoke the console functions without the C Runtime Stack.
