common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

trace: conserve gd register on RISC-V

2020-10-27T20:13:15+00:00

An UEFI application may change the value of the register that gd lives in.
But some of our functions like get_ticks() access this register. So we
have to set the gd register to the U-Boot value when entering a trace
point and set it back to the application value when exiting the trace
point.

trace: clang compatible handling of gd register

2020-07-07T22:23:48+00:00

On ARM systems gd is stored in register r9 or x18. When compiling with
clang gd is defined as a macro calling function gd_ptr(). So we can not
make assignments to gd.

Use function set_gd() for setting the register on ARM.

trace: do not limit trace buffer to 2GiB

2019-07-10T22:52:58+00:00

There is no good reason to limit the trace buffer to 2GiB on a 64bit
system. Adjust the types of the relevant parameters.

trace: make call depth limit customizable

2019-07-10T22:52:58+00:00

Up to now we had hard coded values for the call depth up to which trace
records are created: 200 for early tracing, 15 thereafter. UEFI
applications reach a call depth of 80 or above.

Provide customizing settings for the call trace depth limit and the early
call trace depth limit. Use the old values as defaults.

trace: Tidy up error returns

2019-04-24T02:26:43+00:00

At present many functions in this file return -1. Update them to return a
valid error code. Also tidy up the 'return' statements at the same time,
since these should have a blank line before them.
