* Revert "x86: Convert MMC to driver model"Bin Meng2017-06-274-1/+43
| | | | | | | | | | | | | This reverts commit ddb3ac3c716f56cead695444e65a7ba7b0946555. With MMC converted to driver model, SCSI driver is broken due to zero address access at (ops->read) in block_dread() function. The fix (SCSI driver converted to DM) is ready in u-boot-dm branch, but it is too late for this relese to get that in.

* x86: fsp: Remove the call to set up internal uart in fsp_init()Bin Meng2017-06-051-4/+0
| | | | | | | | | | | | First of all, it's inappropriate to call setup_internal_uart() in a generic API fsp_init(), as CONFIG_INTERNAL_UART is an option that is only available on BayTrail platform. Secondly even for BayTrail, there is no need to call setup_internal_uart() at all, as Intel FSP will do this for us.

* x86: baytrail: Fix boot hang with a debug buildBin Meng2017-06-052-0/+9
| | | | | | | | | | | | It was observed that when -DDEBUG is used to generate a debug build, U-Boot does not boot on MinnowMax board. A workaround is to disable CONFIG_DEBUG_UART. The real issue is that in order to have the debug uart to work, BayTrail SoC needs to be configured so that its internal uart is available to be used as the debug uart.

This is required on some platforms that have the register implemented as dual read/write (such as Baytrail). Prior to this fix the blue USB port on the Minnowboard Max was unusable since USB_HOST_EN0 was set high then immediately set low when USB_HOST_EN1 was written.

* x86: acpi: Fix Windows S3 resume failureBin Meng2017-05-174-2/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot sets up the real mode interrupt handler stubs starting from address 0x1000. In most cases, the first 640K (0x00000 - 0x9ffff) system memory is reported as system RAM in E820 table to the OS. (see install_e820_map() implementation for each platform). So OS can use these memories whatever it wants. If U-Boot is in an S3 resume path, care must be taken not to corrupt these memorie otherwise OS data gets lost. Testing shows that, on Microsoft Windows 10 on Intel Baytrail its wake up vector happens to be installed at the same address 0x1000. While on Linux its wake up vector does not overlap this memory range, but after resume kernel checks low memory range per config option CONFIG_X86_RESERVE_LOW which is 64K by default to see whether a memory corruption occurs during the suspend/resume (it's harmless, but warnings are shown in the kernel dmesg logs). We cannot simply mark the these memory as reserved in E820 table because such configuration makes GRUB complain: unable to allocate real mode page. Hence we choose to back up these memories to the place where we reserved on our stack for our S3 resume work. Before jumping to OS wake up vector, we need restore the original content there.
