x86: Specify -march=core2 to build 64-bit U-Boot proper

With newer kernel.org GCC (7.3.0 or 8.1.0), the u-boot.rom image
built for qemu-x86_64 target does not boot. It keeps resetting
soon after the 32-bit SPL jumps to 64-bit proper. Debugging shows
that the reset happens inside env_callback_init().

000000000113dd85 <env_callback_init>:
 113dd85:       41 54                   push   %r12
 113dd87:       55                      push   %rbp
 113dd88:       31 c0                   xor    %eax,%eax
 113dd8a:       53                      push   %rbx
 113dd8b:       0f 57 c0                xorps  %xmm0,%xmm0

Executing "xorps %xmm0,%xmm0" causes CPU to immediately reset.
However older GCC like 5.4.0 (the one shipped by Ubuntu 16.04)
does not generate such instructions that utilizes SSE for this
function - env_callback_init() and U-Boot boots without any issue.
Explicitly specifying -march=core2 for newer GCC allows U-Boot
proper to boot again. Examine assembly codes of env_callback_init
and there is no SSE instruction in that function hence U-Boot
continues to boot.

core2 seems to be the oldest arch in GCC that supports 64-bit.
Like 32-bit U-Boot build we use -march=i386 which is the most
conservative cpu type so that the image can run on any x86
processor, let's do the same for the 64-bit U-Boot build.

6 years agoEnable CONFIG_TIMER_EARLY with bootstage
Simon Glass [Sun, 2 Sep 2018 23:02:24 +0000 (17:02 -0600)]
Enable CONFIG_TIMER_EARLY with bootstage

In initr_bootstage() we call bootstage_mark_name() which ends up calling
timer_get_us(). This call happens before initr_dm(), which inits driver
model.

On x86 we set gd->timer to NULL in the transition from board_init_f()
to board_init_r(). See board_init_f_r() for this assignment. So U-Boot
knows there is no timer available in the period immediately after
relocation.

On x86 the timer_get_us() call is implemented as calls to get_ticks() and
get_tbclk(). Both of these call dm_timer_init() to set up the timer, if
gd->timer is NULL and the early timer is not available.

However dm_timer_init() cannot succeed before initr_dm() is called.

So it seems that on x86 if we want to use CONFIG_BOOTSTAGE we must enable
CONFIG_TIMER_EARLY. Update the Kconfig to handle this.

Note: On most architectures we can rely on the pre-relocation memory still
being available, so that gd->timer pointers to a valid timer device and
everything works correctly. Admittedly this is not strictly correct since
the timer device is set up by pre-relocation U-Boot, but normally this is
fine. On x86 the 'CAR' (cache-as-RAM) memory used by pre-relocation U-Boot
disappears in board_init_f_r() and any attempt to access it will hang.
This is the reason why we must mark the timer as invalid when we get to
board_init_f_r().
