Jeff Johnston 5eb4a1666d or1k: set heap start for optimsoc-gzll
- With the gzll kernel we have two different loading options:

  - If the image is loaded to the global memory, the bootstrapping
    loads the kernel to local memory. Applications are loaded on
    demand. The heap then starts right after bss.

  - If the image is pre-loaded to the local memory it includes the
    application binaries right after bss. The heap then starts after
    the application objects.

- We can check if this is a gzll kernel as it has the string "gzll" at
  0x2000. At 0x200c we then find the end of the application objects in
  the image. If there is no global memory we set _or1k_heap_start to
  this value.

    * or1k/boards/optimsoc.S: Heap for gzll kernel

Jeff Johnston 58efeedd16 or1k: Make heap start configurable
- Previously the heap started right after the bss section. This can now
  be configured by changing the _or1k_heap_start symbol that defaults to
  the old value (&end). In board_init_early, we can now set this to
  another value.

    * or1k/sbrk.c: Allow for different heap start

Jeff Johnston aa26b78462 or1k: UART also accept timeout interrupt
- The UART interrupt only handled receiver FIFO full interrupts, but we
  also want to handle timeout interrupts.

Jeff Johnston 58e5719a0e Bug fix in timer for or1k

Jeff Johnston b46d3b5536 Store entire context for or1k
- Store the exception program counter (from EPCR) and exception status
  register (from ESR) also during the exception. A runtime system may
  replace them thereby to implement a thread switch.

    * or1k/exception-asm.S: Store missing state
2015-05-27 13:30:20 +02:00
Jeff Johnston a6342974b0 Fix exception stack frame for or1k
- We do not need a red zone here, as we do not operate on the current
  stack, but always use the clear exception stack. Also reserve two
  extra words for the context to store EPCR and ESR.

    * or1k/crt0.S: Fix exception stack frame
    * or1k/exception-asm.S: ditto
2015-05-27 13:30:19 +02:00
Jeff Johnston 132030fcf2 Fix interrupt handling for or1k.
- During interrupt handling the PICSR, table pointers and current
  interrupt line have been saved in incorrect registers and/or stored on
  the stack.

- Save the pointer in r16/r18, PICSR in r20 and the current interrupt
  line in r22. Those are callee-saved registers, so that the register
  values will be preserved.

        * or1k/interruts-asm.S: Change registers to callee-saved.

The mcore simulator has a unique set of syscall numbers.  Add a header
that matches reality since the common one doesn't.

Mike Frysinger 6803327326 libgloss: arm: fix copy & paste in syscall.h

but the header comment is no longer accurate -- this isn't the general
file anymore.
