[PATCH 0/4] Reduce TI-SCI driver size to fix am65x_evm_r5 build

[Andrew Davis]

Hi All,

The am65x_evm_r5_defconfig build was overflowing the SRAM area by 16 bytes
on the latest master with the gcc-arm-9.2-2019.12 compiler. Lets do some
simple cleanups in one of the largest drivers on these K3 systems and give
us some more headroom for new features.

[PATCH 1/4] firmware: ti_sci: Reduce output on ti_sci_do_xfer error

[Andrew Davis]

This ti_sci_do_xfer() function already prints out the reason for the
failure, and the caller of each of these functions should also notify
the user of the failed task. Remove this extra level of error message.

[PATCH 2/4] firmware: ti_sci: Factor out message alloc failed message

[Andrew Davis]

We don't need to print the same message in every location, just
print it in the function that fails and remove all the extra
message printouts.

[PATCH 3/4] firmware: ti_sci: Remove inline keyword from functions

[Andrew Davis]

The inline hint is not needed here, the compiler will do the right thing
based on if we are compiling for speed or for code size. In this case the
inline causes this function to be placed inside each callsite which is
not the right thing to do for either speed nor size. There is no
performance benefit to this due to the larger function size reducing
cache locality, but there is a huge size penalty. Remove inline keyword.

[PATCH 4/4] firmware: ti_sci: Move ACK checking to ti_sci_do_xfer() function

[Andrew Davis]

We can check if the message was acknowledged in the common
ti_sci_do_xfer() which lets us remove it from after each call to this
function. This simplifies the code and reduces binary size.
