* x86: Don't touch IA32_APIC_BASE MSR on Intel QuarkBin Meng2016-05-23-12/+16
| | | | | | | | | | | Intel Quark processor core provides an integrated Local APIC but does not support the IA32_APIC_BASE MSR. As a result, the Local APIC is always globally enabled and the Local APIC base address is fixed at 0xfee00000. Attempting to access the IA32_APIC_BASE MSR causes a general protection fault.

* x86: crownbay: Disable boot stage supportBin Meng2016-05-23-3/+0
| | | | | | | | | | | | | | | It is observed that when enabling boot stage support, occasionally the board reboots during boot over and over again, and eventually boots to shell. This was seen on my board, but not on Jian's board. Debugging shows that the TSC timer calibration against PIT fails as boot stage APIs utilize timer in a very early stage and at that time TSC/PIT may not be stable enough for the calibration to pass. Disable it for now. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Cc: Jian Luo <Jian.Luo4@boschrexroth.de> Reviewed-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | BayTrail integrates an internal ns15550 compatible UART (PNP0501). Its IRQ is hardwired to IRQ3 in old revision chipset, but in newer revision one IRQ4 is being used for ISA compatibility. Handle this correctly in the ASL file. Linux does not need this ASL, but Windows need this to correctly discover a COM port existing in the system so that Windows can show it in the 'Device Manager' window, and expose this COM port to any terminal emulation application.

* x86: acpi: Switch to ACPI mode by ourselves instead of requested by OSPMBin Meng2016-05-23-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Per ACPI spec, during ACPI OS initialization, OSPM can determine that the ACPI hardware registers are owned by SMI (by way of the SCI_EN bit in the PM1_CNT register), in which case the ACPI OS issues the ACPI_ENABLE command to the SMI_CMD port. The SCI_EN bit effectively tracks the ownership of the ACPI hardware registers. However since U-Boot does not support SMI, we report all 3 fields in FADT (SMI_CMD, ACPI_ENABLE, ACPI_DISABLE) as zero, by following the spec who says: these fields are reserved and must be zero on system that does not support System Management mode. U-Boot seems to behave in a correct way that the ACPI spec allows, at least Linux does not complain, but apparently Windows does not think so. During Windows bring up debugging, it is observed that even these 3 fields are zero, Windows are still trying to issue SMI with hardcoded SMI port address and commands, and expecting SCI_EN to be changed by the firmware. Eventually Windows gives us a BSOD (Blue Screen of Death) saying ACPI_BIOS_ERROR and refuses to start. To fix this, turn on the SCI_EN bit by ourselves. With this patch, now U-Boot can install and boot Windows 8.1/10 successfully with the help of SeaBIOS using legacy interface (non-UEFI mode).

* x86: Fix up PIRQ routing table checksum earlierBin Meng2016-05-23-4/+4
| | | | | | | | | | | | | | | | PIRQ routing table checksum is fixed up in copy_pirq_routing_table(), which is fine if we only write the configuration table once. But with the SeaBIOS case, when we write the table for the second time, the checksum will be fixed up to zero per the checksum algorithm, which is caused by the checksum field not being zero before fix up, since the checksum has already been calculated in the first run. To fix this, move the checksum fixup to create_pirq_routing_table(), so that copy_pirq_routing_table() only does what its function name suggests: copy the table to somewhere else.
