      Multi-console: Deprecate the `finish_console_register` macro · cc5859ca
      Soby Mathew authored
      
      
      The `finish_console_register` macro is used by the multi console
      framework to register the `console_t` driver callbacks. It relied
      on weak references to the `ldr` instruction to populate 0 to the
      callback in case the driver has not defined the appropriate
      function. Use of `ldr` instruction to load absolute address to a
      reference makes the binary position dependant. These instructions
      should be replaced with adrp/adr instruction for position independant
      executable(PIE). But adrp/adr instructions don't work well with weak
      references as described in GNU ld bugzilla issue 22589.
      
      This patch defines a new version of `finish_console_register` macro
      which can spcify which driver callbacks are valid and deprecates the
      old one. If any of the argument is not specified, then the macro
      populates 0 for that callback. Hence the functionality of the previous
      deprecated macro is preserved. The USE_FINISH_CONSOLE_REG_2 define
      is used to select the new variant of the macro and will be removed
      once the deprecated variant is removed.
      
      All the upstream console drivers have been migrated to use the new
      macro in this patch.
      
      NOTE: Platforms be aware that the new variant of the
      `finish_console_register` should be used and the old variant is
      deprecated.

      drivers: ti: uart: remove UART_FCR writes · 8178ea7c
      Varun Wadekar authored
      
      
      This patch removes the code that touched UART_FCR, from
      console_core_putc(). The check for whether transmit FIFO is
      full is sufficient before writing to UART TX FIFO. In fact
      setting UARTFCR_TXCLR immediately after a byte is written to
      FIFO might even result in loss of that byte, if UART hasn't
      sent that byte out yet.

      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.

      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.

      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.
