2015-07-14x86: queensbay: Change PCIe root ports' interrupt routingBin Meng
So far interrupt routing works pretty well for any on-chip devices on Intel Crown Bay. When inserting any PCIe card to any PCIe slot, Linux kernel is smart enough to do interrupt swizzling and figure out device's irq using its parent bridge's interrupt routing info all the way up to its root port. In U-Boot all PCIe root ports' interrupts were routed to PIRQ E/F/G/H before, while actually all PCIe downstream ports received INTx are routed to PIRQ A/B/C/D directly and not configurable. Now we change this mapping so that any external PCIe device can work correctly. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-07-14x86: Generate a valid MultiProcessor (MP) tableBin Meng
Implement write_mp_table() to create a minimal working MP table. This includes an MP floating table, a configuration table header and all of the 5 base configuration table entries. The I/O interrupt assignment table entry is created based on the same information used in the creation of PIRQ routing table from device tree. A check duplicated entry logic is applied to prevent writing multiple I/O interrupt entries with the same information. Use a Kconfig option GENERATE_MP_TABLE to tell U-Boot whether we need actually write the MP table at the F seg, just like we did for PIRQ routing and SFI tables. With MP table existence, linux kernel will switch to I/O APIC and local APIC to process all the peripheral interrupts instead of 8259 PICs. This takes full advantage of the multicore hardware and the SMP kernel. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-07-14x86: Add MultiProcessor (MP) table APIsBin Meng
The MP table provides a way for the operating system to support for symmetric multiprocessing as well as symmetric I/O interrupt handling with the local APIC and I/O APIC. We provide a bunch of APIs for U-Boot to write the floating table, configuration table header as well as base and extended table entries.

2015-07-14x86: Reduce PIRQ routing table sizeBin Meng
There is no need to populate multiple irq info entries with the same bus number and device number, but with different interrupt pin. We can use the same entry to store all the 4 interrupt pin (INT A/B/C/D) routing information to reduce the whole PIRQ routing table size.

2015-07-14x86: Ignore function number when writing PIRQ routing tableBin Meng
In fill_irq_info() pci device's function number is written into the table, however this is not really necessary. The function number can be anything as OS doesn't care about this field, neither does the PIRQ routing specification. Change to always writing 0 as the function number.

2015-07-14x86: queensbay: Correct Topcliff device irqsBin Meng
There are 4 usb ports on the Intel Crown Bay board, 2 of which are connected to Topcliff usb host 0 and the other 2 connected to usb host 1. USB devices inserted in the ports connected to usb host 1 cannot get detected due to wrong IRQ assigned to the controller. Actually we need apply the PCI interrupt pin swizzling logic to all devices on the Topcliff chipset when configuring the PIRQ routing. This was observed on usb ports, but device 6 and 10 irqs are also wrong. Correct them all together. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-07-14x86: Move lapic_setup() call into init_bsp()Bin Meng

2015-07-14x86: fsp: Move FspInitEntry call to board_init_f()Bin Meng
The call to FspInitEntry is done in arch/x86/lib/fsp/fsp_car.S so far. It worked pretty well but looks not that good. Apart from doing too much work than just enabling CAR, it cannot read the configuration data from device tree at that time. Now we want to move it a little bit later as part of init_sequence_f[] being called by board_init_f(). This way it looks and works better in the U-Boot initialization path. Due to FSP's design, after calling FspInitEntry it will not return to its caller, instead it jumps to a continuation function which is given by bootloader with a new stack in system memory. The original stack in the CAR is gone, but its content is perserved by FSP and described by a bootloader temporary memory HOB. Technically we can recover anything we had before in the previous stack, but that is way too complicated. To make life much easier, in the FSP continuation routine we just simply call fsp_init_done() and jump back to car_init_ret() to redo the whole board_init_f() initialization, but this time with a non-zero HOB list pointer saved in U-Boot's global data so that we can bypass the FspInitEntry for the second time.

2015-07-14x86: fsp: Load GDT before calling FspInitEntryBin Meng
Currently the FSP execution environment GDT is setup by U-Boot in arch/x86/cpu/start16.S, which works pretty well. But if we try to move the FspInitEntry call a little bit later to better fit into U-Boot's initialization sequence, FSP will fail to bring up the AP due to #GP fault as AP's GDT is duplicated from BSP whose GDT is now moved into CAR, and unfortunately FSP calls AP initialization after it disables the CAR. So basically the BSP's GDT still refers to the one in the CAR, whose content is no longer available, so when AP starts up and loads its segment register, it blows up. To resolve this, we load GDT before calling into FspInitEntry. The GDT is the same one used in arch/x86/cpu/start16.S, which is in the ROM and exists forever.

2015-07-05sunxi: rsb: Enable R_PIO clock before configuring external pinsChen-Yu Tsai
The original code was configuring the external pins after enabling the R_PIO clock, which meant the configuration never made it to the pin controller the first time in SPL. Why this was working before is uncertain. Maybe the state was left from a previous boot sequence, or RSB just happened to be the default configuration. However with some A33 chips, SPL failed to configure the PMIC. This was seen by me and Maxime on the Sinlinx SinA33 dev board. Reordering the calls fixed this.
