commit 46bf82ac413f478ffd2afe684b8926ea09509c4c
Author: Brandon Breitenstein <brandon.breitenstein(a)intel.com>
Date: Thu Jan 5 12:47:27 2017 -0800
apollolake: Update UPD header files for FSP 1.3.0
These updated header files contain USB tuning parameters as well as
some general cleanup of unused parameters in the UPD Headers. This
patch along with the upcoming FSP 1.3.0 release will allow for USB
tuning on apollolake platforms.

commit 86885430183e96ae52ee679b5dda4079e35590e6
Author: Brandon Breitenstein <brandon.breitenstein(a)intel.com>
Date: Thu Jan 5 12:47:27 2017 -0800
apollolake: Update UPD header files for FSP 1.3.0
These updated header files contain USB tuning parameters as well as
some general cleanup of unused parameters in the UPD Headers. This
patch along with the upcoming FSP 1.3.0 release will allow for USB
tuning on apollolake platforms.

commit 40fc051ca813e8ec59ace47c52b130fbe0021baa
Author: Iru Cai <mytbk920423(a)gmail.com>
Date: Sat Oct 29 23:37:42 2016 +0800
buildgcc: Update GCC, Binutils, GMP, MPFR, GDB and IASL
- GCC gets updated from 5.2.0 to 6.3.0:
For RISC-V, I rebase riscv-gnu-toolchain on gcc-6_2_0-release and make a diff:
git diff --src-prefix=original-gcc/ --dst-prefix=gcc-6.2.0/ gcc-6_2_0-release
- Binutils goes from 2.26.1 to 2.27:
There is a build error for MIPS gold so I add patch for it.
The RISC-V patches are based on riscv-gnu-toolchain revision 910ea19, and
the riscv-binutils-gdb tree that generated the binutils-2.27_riscv.patch
has lost. For GCC, the gcc-6.2.0_riscv.patch can still be used in GCC 6.3.0.
- GMP gets a bump from 6.1.0 to 6.1.2
- MPFR is updated from 3.1.4 to 3.1.5
- GDB is upgraded from 6.1.1 to 6.1.2
- IASL is changed from 20160831 to 20161222

-+ (2) The target of pre-reload load sequences should not be used

-+ assigned one value, reload can rematerialize that value
-+ on demand, rather than spill it to the stack.
-+
-+ (3) If we allowed pre-reload passes like combine and cse to recreate
-+ complex load sequences, we would want to be able to split the
-+ sequences before reload as well, so that the pre-reload scheduler
-+ can see the individual instructions. This falls foul of (2);
-+ the splitter would be forced to reuse the target register for
-+ intermediate results.
-+
-+ (4) We want to define complex load splitters for combine. These
-+ splitters can request a temporary scratch register, which avoids
-+ the problem in (2). They allow things like:

-+ (set (reg T1) (high SYM))
-+ (set (reg T2) (low (reg T1) SYM))

++ (2) The target of pre-reload load sequences should not be used
++ to store temporary results. If the target register is only
++ assigned one value, reload can rematerialize that value
++ on demand, rather than spill it to the stack.
++
++ (3) If we allowed pre-reload passes like combine and cse to recreate
++ complex load sequences, we would want to be able to split the
++ sequences before reload as well, so that the pre-reload scheduler
++ can see the individual instructions. This falls foul of (2);
++ the splitter would be forced to reuse the target register for
++ intermediate results.
++
++ (4) We want to define complex load splitters for combine. These
++ splitters can request a temporary scratch register, which avoids
++ the problem in (2). They allow things like:
++
++ (set (reg T1) (high SYM))
++ (set (reg T2) (low (reg T1) SYM))
++ (set (reg X) (plus (reg T2) (const_int OFFSET)))

riscv: get SBI calls to work
SBI calls, as it turned out, were never right.
They did not set the stack correctly on traps.
They were not correctly setting the MIP instead of the SIP
(although this was not really well documnented).
On Harvey, we were trying to avoid using them,
and due to a bug in SPIKE, our avoidance worked.
Once SPIKE was fixed, our avoidance broke.
This set of changes is tested and working with Harvey
which, for the first time, is making SBI calls.
It's not pretty and we're going to want to rework
trap_util.S in coming days.
