x86: tangier: acpi: Add GPIO card detection to SDHCI #2

2021-09-22T13:50:35+00:00

On Intel Tangier the SDHCI #2 provides SD card connection. Add GPIO card detection for it. Fixes: 39665beed6f7 ("x86: tangier: Enable ACPI support for Intel Tangier") BugLink: https://github.com/edison-fw/meta-intel-edison/issues/135 Signed-off-by: Andy Shevchenko Acked-by: Bin Meng

x86: mtrr: Abort if requested size is not power of 2

2021-08-02T07:11:41+00:00

The size parameter of mtrr_add_request() and mtrr_set_next_var() shall be power of 2, otherwise the logic creates a mask that does not meet the requirement of IA32_MTRR_PHYSMASK register. Programming such a mask value to IA32_MTRR_PHYSMASK generates #GP.

x86: Add function comments to cb_sysinfo.h

Add a function comment for get_coreboot_info() and a declaration for cb_get_sysinfo(), since this may be called from elsewhere. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Update the MP constants to avoid conflicts

2021-07-15T11:50:04+00:00

These constants conflict with error codes returned by the MP implementation when something is wrong. In particular, mp_first_cpu() returns MP_SELECT_BSP when running without multiprocessing enabled. Since this is -2, it is interpreted as an error by callers, which expect a positive CPU number for the first CPU. Correct this by using a different range for the pre-defined CPU numbers, above zero and out of the range of possible CPU values. For now it is safe to assume there are no more than 64K CPUs. This fixes the 'mtrr' command when CONFIG_SMP is not enabled. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: coral: Allow init of debug UART in U-Boot proper

2021-03-27T02:04:30+00:00

At present the debug UART is only set up in SPL, on the assumption that the boot flow will always pass through there. When booting from coreboot, SPL is not used, so the debug UART is not available. Move the code into a common place so that it can be used in U-Boot proper also. Add the required init to start_from_spl.S as well. Signed-off-by: Simon Glass

x86: coreboot: Update parsing of the latest sysinfo

2021-03-27T00:59:59+00:00

Quite a few new tag types have been added over the years. Bring these into U-Boot so that all required tags can be parsed. Add a proper comment to struct sysinfo_t while we are here, since many of the meanings are not obvious. Signed-off-by: Simon Glass
