Hello Subrata Banik, build bot (Jenkins),
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/84142?usp=email
to look at the new patch set (#4).
Change subject: src/include/: Introducing a new BIT_32(x) macro.
......................................................................
src/include/: Introducing a new BIT_32(x) macro.
This new macro addition ensures the shift operation does not
exceed the 32-bit width of the GEN_PMCON_A register.
Details-
On a 64-bit system, 1ul will typically be 64 bits wide.
The left shift can accommodate values of x up to 63 without overflowing.
But `GEN_PMCON_A` register width is 32-bit hence, adding new BIT_32(x)
to limit the register to max 32-bit width.
