/* A lot of complication here is taken away because:
*
* 1) We handle one interrupt and return, sitting in a loop and moving across
* all the pending IRQ bits in the cause register is _NOT_ the answer, the
* common case is one pending IRQ so optimize in that direction.
*
* 2) We need not check against bits in the status register IRQ mask, that
* would make this routine slow as hell.
*
* 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
* between like BSD spl() brain-damage.
*
* Furthermore, the IRQs on the MIPS board look basically (barring software
* IRQs which we don't use at all and all external interrupt sources are
* combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
*
* MIPS IRQ Source
* -------- ------
* 0 Software (ignored)
* 1 Software (ignored)
* 2 Combined hardware interrupt (hw0)
* 3 Hardware (ignored)
* 4 Hardware (ignored)
* 5 Hardware (ignored)
* 6 Hardware (ignored)
* 7 R4k timer (what we use)
*
* Note: On the SEAD board thing are a little bit different.
* Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
* wired to UART1.
*
* We handle the IRQ according to _our_ priority which is:
*
* Highest ---- R4k Timer
* Lowest ---- Combined hardware interrupt
*
* then we just return, if multiple IRQs are pending then we will just take
* another exception, big deal.

The code is intended to decompress kernel, being compressed using lzma utility
build using 7zip LZMA SDK. This utility is located in the LZMA_Alone directory
decompressor code expects that your .trx file consist of three partitions:
1) decompressor itself (this is gziped code which pmon/cfe will extract and run
on boot-up instead of real kernel)
2) LZMA compressed kernel (both streamed and regular modes are supported now)
3) Root filesystem
Please be sure to apply the following patch for use this new trx layout (it will
allow using both new and old trx files for root filesystem lookup code)
