-/* A lot of complication here is taken away because:

- *
- * 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)
