This is an initial specification of the eCos Hardware Abstraction Layer (HAL). The HAL abstracts
the underlying hardware of a processor architecture and/or the
platform to a level sufficient for the eCos kernel to be ported onto
that platform.
Caveat: This document is an informal description of the HAL capabilities and
is not intended to be full documentation, although it may be used as a
source for such. It also describes the HAL as it is currently
implemented for the architectures targeted in this release. It most
closely describes the HALs for the MIPS, I386 and PowerPC HALs. Other
architectures are similar but may not be organized precisely as
described here.
