From: Pierre Gondois <pierre.gond...@arm.com> The '-tc' option of the Intel iASL compiler facilitates generation of AML code in a C array. This AML code is output to a .hex file. The .hex file can be included from a C source file, thereby allowing one to run a fix-up code in C.
For example, this technique can be used to patch the resource data elements that describe the base address or interrupt number for a device, before installing the ACPI table. To implement this feature two conditions need to be satisfied: - The ASL and C files must be included in the sources section of the same .inf file for the module. - The ASL files are pre-processed and compiled before the C files (so that the .hex file include dependency is satisfied). This patch resolves the dependency by sorting the CODA_TARGET list for the module being built and placing the .aml files at the very beginning of the list. Signed-off-by: Pierre Gondois <pierre.gond...@arm.com> --- The changes can be seen at https://github.com/PierreARM/edk2/commits/676_build_asl_first_v1 Notes: v1: - Sort .aml files first in the CODA_TARGET to build [Pierre] them before other files.
