The MVME2100 is a Motorola VMEbus board which is similar to the other
|
||||
Motorola PowerPC boards supported by this BSP. But it does not support
|
||||
the Motorola CPU Configuration Register. This makes it impossible to
|
||||
dynamically probe and determine that you are executing on this board
|
||||
variant. So this BSP variant must be explicitly built to only support
|
||||
the MVME2100. The complete list of differences found so far is:
|
||||
|
||||
* No CPU Configuration Register
|
||||
* one COM port
|
||||
* COM port is on PCI IRQ not ISA IRQ
|
||||
* limited on RAM (32 or 64 MB)
|
||||
* uses the EPIC interrupt controller on the MPC8240
|
||||
* does not have an ISA bus but has an ISA I/O address space
|
||||
* cannot set DBAT2 in bspstart like other variants because
|
||||
there are PCI/ISA Interrupt Acknowledge registers at this space
|
||||
This BSP may have left some PCI memory uncovered
|
||||
* PPCBug starts programs with vectors still in ROM
|
||||
|
||||
Supported Features:
|
||||
- Interrupt driven console using termios
|
||||
- Network device driver
|
||||
- Real-Time Clock driver
|
||||
- Clock Tick Device Driver
|
||||
|
||||
Things to address:
|
||||
- Does not return to monitor
|
||||
- Level 1 cache is disabled for now
|
||||
- Check on trying to read CPU Configuration Register for CHRP/Prep for PCI
|
||||
and report a failure if in the wrong mode. May be able to set the model
|
||||
but it may be hard to test if we break PPCBug.
|
||||
- Use NVRAM for network configuration information
|
||||
|
||||
BSP Features Not Implemented:
|
||||
- VMEbus mapped in but untested
|
||||
- OpenPIC features not required for BSP are not supported

* Entry point information used by bootloader code
|

* The issue with this file is getting it loaded at the right place.
|
||||
* The first vector MUST be at address 0x????0100.
|
||||
* How this is achieved is dependant on the tool chain.
|
||||
*
|
||||
* However the basic mechanism for ELF assemblers is to create a
|
||||
* section called ".vectors", which will be loaded to an address
|
||||
* between 0x????0000 and 0x????0100 (inclusive) via a link script.
|
||||
*
|
||||
* The basic mechanism for XCOFF assemblers is to place it in the
|
||||
* normal text section, and arrange for this file to be located
|
||||
* at an appropriate position on the linker command line.
|
||||
*
|
||||
* The variable 'PPC_VECTOR_FILE_BASE' must be defined to be the
|
||||
* offset from 0x????0000 to the first location in the file. This
|
||||
* will usually be 0x0000 or 0x0100.
