2017-12-02arch/riscv: Remove the current SBI implementationJonathan Neuschäfer
This Supervisor Binary Interface, which is based on a page of code that's provided to operating systems by the M-mode software, has been superseded by a different (currently not really documented) SBI, which is based on directly executing ECALLs instructions. Thus some of our code becomes obsolete. Just rip it out until we implement the new SBI.

2017-11-21arch/x86: Write ACPI DBG2 table only if the device has been enabledMario Scheithauer
The commit 93bbd41e (soc/intel: Enable ACPI DBG2 table generation) causes a crash on the mainboard mc_apl1. On this mainboard all internal SOC UARTs in the devicetree are switched off. As a result, no resources are allocated to the UARTs. The function find_resource() expects an existing resource. Otherwise, the CPU will stop. It should therefore not only be queried whether a device is present, but also whether it is enabled.

2017-10-29arch/x86: Restore forwarding table on resume for non EARLY_EBDA_INITFurquan Shaikh
In commit c06a3f72 (arch/x86: initialize EBDA in S3 and S0/S5 path), BDA and EBDA are wiped in the resume path. It results in coreboot forwarding table address being wiped out since it is stored in the BDA. This issue was resolved for platforms using EARLY_EBDA_INIT in commit f46a9a0d (arch/x86: restore forwarding table on resume for EARLY_EBDA_INIT). However platforms that do not use EARLY_EBDA_INIT still run into the same issue and hence cbmem does not work on resume. This change fixes the issue by using the stash/restore of forwarding table address for all platforms using BDA. BUG=b:68412690 TEST=Verified that cbmem works on S3 resume for coral.

2017-07-13arch/x86/assembly_entry: Align stack for car_stage_entryMarshall Dawson
At process _start, the stack is expected to be aligned to a 16-byte boundary. Upon entry to any function the stack frame must have the end of any arguments also aligned. In other words the value of %esp+4 or %rsp+8 is always a multiple of 16 (1). Align the stack down and change the method for executing car_stage_entry from jmp to call which should preserve proper alignment regardless of a 32- or 64-bit build. Although 4-byte alignment is the minimum requirement for i386, some AMD platforms use SSE instructions which expect 16-byte. 1) http://wiki.osdev.org/System_V_ABI See "Initial Stack and Register State" and "The Stack Frame" in the supplements.
