| * ARM: uniphier: support USB boot mode for ProXstream2 / PH1-LD6b SoCMasahiro Yamada2016-02-144-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB boot code is too fat and complicated to be included in SPL (at least for now). So, it was implemented as a separate project (what we call USB-loader). The expected boot sequence is as follows: Boot ROM -> USB-loader -> SPL -> U-Boot proper The USB-loader loads the SPL and U-Boot proper from a USB memory onto the locked L2 cache. Then, SPL needs to copy the U-Boot proper to DRAM, so this mode looks like a NOR boot from the view of SPL. However, we want to distinguish between (genuine) NOR boot and USB boot in some places.

| * ARM: uniphier: create early page table at run-timeMasahiro Yamada2016-02-143-38/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UniPhier SoCs are not equipped with dedicated on-chip SRAM. Instead, locked outer cache is used as RAM area during the early boot stage where DRAM is not ready yet. This effectively means MMU must be always enabled while we are in SPL. Currently, the SPL image for UniPhier SoCs contains the page table statically defined at compile time. It has been a burden because the 16KB page table occupies a quarter memory footprint of the 64KB SPL image. Finally, there is no more room to implement new features in SPL. Setting aside the NOR boot mode, this issue can be solved by creating the page table onto RAM at run time. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
| * ARM: uniphier: change stack pointer address for SPLMasahiro Yamada2016-02-141-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | No special reason for the current stack address 0x0ff08000. Change it to 0x00100000 to simplify the init_page_table. There are two types of SoCs in terms of the load address of SPL. [1] PH1-sLD3, PH1-LD4, PH1-sLD8 SPL is loaded at 0x00040000-0x0004ffff [2] PH1-Pro4, PH1-Pro5, ProXstream2, PH1-LD6b SPL is loaded at 0x00100000-0x0010ffff The new stack area (0x000f8000-0x00100000) should be safe for all the cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With recent DM PCI changes to vesa_fb driver, external graphics card does not work any more. This is because: after setting the function disable bit, IGD and SDVO devices will disappear in the PCI configuration space. This however creates an inconsistent state from a driver model PCI controller point of view, as these two PCI devices are still attached to its parent's child device list as maintained by the driver model. Some driver model PCI APIs like dm_pci_find_class() used in the vesa_fb driver, are referring to the list to speed up the finding process instead of re-enumerating the whole PCI bus, so it gets the stale cached data which is wrong. To fix this, manually remove these two devices. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
