[U-Boot] [PATCH v3 0/6] x86: bootstage: Fix bootstage operation on link

[Simon Glass]

Recent bootstage changes have provoked problems with chromebook_link.
Bootstage uses the timer before driver model is ready, but link uses
driver model for the timer.

This series:
- Updates the TSC timer to make the bootstage work before DM is ready
- Provides a way to have a separate setting for record count in SPL to
    save memory
- Tidies up a few bootstage options that are no-longer needed

This fixes booting on link which is currently broken.

Changes in v3:
- Bracket access to gd->timer with an #ifdef

Changes in v2:
- Update to support the early timer
- Rebase on top of early timer code and simplify slightly
- Add new patch to enable early timer for chromebook_link

Simon Glass (6):
  board_f: Drop the timer after relocation
  dm: x86: Allow TSC timer to be used before DM is ready
  dm: x86: Update timer_get_boot_us to work before DM is ready
  bootstage: Drop unused options
  bootstage: Provide a separate record count setting for SPL
  x86: Enable early timer for chromebook_link
