As DEBUG is no Kconfig symbol, we can't use the IS_ENABLED() macros. This patch switches to the unfortunately necessary #ifdef usage again to make it work correctly. Signed-off-by: Stefan Roese <sr@denx.de>

/**
|
|
* Module to support operations on bitmap of cores. Coremask can be used to
|
|
* select a specific core, a group of cores, or all available cores, for
|
|
* initialization and differentiation of roles within a single shared binary
|
|
* executable image.
|
|
*
|
|
* The core numbers used in this file are the same value as what is found in
|
|
* the COP0_EBASE register and the rdhwr 0 instruction.
|
|
*
|
|
* For the CN78XX and other multi-node environments the core numbers are not
|
|
* contiguous. The core numbers for the CN78XX are as follows:
|
|
*
|
|
* Node 0: Cores 0 - 47
|
|
* Node 1: Cores 128 - 175
|
|
* Node 2: Cores 256 - 303
|
|
* Node 3: Cores 384 - 431
|
|
*
|
|
* The coremask environment generally tries to be node agnostic in order to
|
|
* provide future compatibility if more cores are added to future processors
|
|
* or more nodes are supported.
