| * | | ARM64: zynqmp: Add support for USB ulpi phy reset via mode pinsMichal Simek2016-09-22-1/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mode pins can be used as output for reset. Xilinx boards are using this feature as additional way how to reset USB phys and also others chips on the boards. Mode1 is used on all these boards for this feature. Let SPL toggle reset on this pin by default. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
| * | | ARM64: zynqmp: Add support for DFU from SPLMichal Simek2016-09-22-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SPL needs to have bigger stack size because of USB. Simple malloc needs to be disabled because dfu code requires different allocation functions. There is no space in OCM that's why random place in DDR is used. BOOTD must be disabled because it is causing compilation error. All variables are disabled and used only variables valid for DFU because they are simple huge. Including automatic variables added by CONFIG_ENV_VARS_UBOOT_CONFIG. Hardcode addresses for u-boot, atf, kernel and dtb just for SPL DFU code. Enable SPL DFU for zcu100. Create new usb_dfu_spl variable just to run Linux kernel loaded in SPL. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

| * | MIPS: Hang if run on a secondary CPUPaul Burton2016-09-21-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some systems are configured such that multiple CPUs begin running from their reset vector following a system reset. If this occurs then U-Boot will be run on multiple CPUs simultaneously, which causes all sorts of issues as the multiple instances of U-Boot clobber each other. Prevent this from happening by simply hanging with an infinite loop if we run on a CPU whose ID, as determined by GlobalNumber or EBase.CPUNum as appropriate, is non-zero.

| * | MIPS: Fix cache maintenance in relocate_code & simplifyPaul Burton2016-09-21-26/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The relocate_code function was handling cache maintenance incorrectly. It copied U-Boot to its new location, flushed the caches & then proceeded to apply relocations & jump to the new code without flushing the caches again. This is problematic as the instruction cache could potentially have already fetched instructions that hadn't had relocs applied. Rework this to perform the flush_cache call using the code in the original copy of U-Boot, after having applied relocations to the new copy of U-Boot. The new U-Boot can then be jumped to safely once that cache flush has been performed. As part of this, since the old U-Boot is used up until after that cache flush, complexity around loading values from the GOT using a jump & link instruction & loads from a table is removed. Instead we can simply load the needed values with PTR_LA fromt the original GOT. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | boston: Introduce support for the MIPS Boston development boardPaul Burton2016-09-21-0/+241
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces support for building U-Boot to run on the MIPS Boston development board. This is a board built around an FPGA & an Intel EG20T Platform Controller Hub, used largely as part of the development of new CPUs and their software support. It is essentially the successor to the older MIPS Malta board. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | MIPS: Ensure cache ops complete in mips_cache_resetPaul Burton2016-09-21-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that cache operations complete before returning from mips_cache_reset by placing a completion barrier (sync instruction) before the return. Without this there is no guarantee that the cache ops will complete before any subsequent memory accesses, since they are indexed cache ops & thus not implicitly ordered with memory accesses. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | MIPS: Clear hazard between TagLo writes & cache opsPaul Burton2016-09-21-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Writing to the coprocessor 0 TagLo registers introduces an execution hazard in that we need that write to complete before any cache instructions execute. Ensure that hazard is cleared by inserting an ehb instruction between the TagLo writes & cache op loop. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | MIPS: Ensure Config.K0=2 applies before any memory accessesPaul Burton2016-09-21-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During boot we set Config.K0=2 (uncached) such that any accesses to the kseg0 memory region are performed uncached before the caches are initialised. This write to the Config register introduces an execution hazard between it & any following memory accesses (such as the load of _gp), which we need to clear in order to ensure those memory accesses are actually performed uncached. Clear this execution hazard with the insertion of an ehb execution hazard barrier instruction. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | MIPS: Malta: Enable CM & L2 supportPaul Burton2016-09-21-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Enable support for the MIPS Coherence Manager & L2 caches on the MIPS Malta board, removing the need for us to attempt to bypass the L2 during boot (which would fail with recent CPUs that expose L2 config via the CM anyway). Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | MIPS: Join the coherent domain when a CM is presentPaul Burton2016-09-21-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MIPS Linux expects the bootloader to leave the boot CPU a member of the coherent domain when running on a system with a CM, and we will need to do so if we wish to make use of IOCUs to have cache-coherent DMA in U-Boot (and on some systems there is no choice in that matter). When a CM is present, join the coherent domain after completing cache initialisation. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | MIPS: L2 cache supportPaul Burton2016-09-21-6/+291
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for initialising & maintaining L2 caches on MIPS systems. The L2 cache configuration may be advertised through either coprocessor 0 or the MIPS Coherence Manager depending upon the system, and support for both is included. If the L2 can be bypassed then we bypass it early in boot & initialise the L1 caches first, such that we can start making use of the L1 instruction cache as early as possible. Otherwise we initialise the L2 first such that the L1s have no opportunity to generate access to the uninitialised L2. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

| * | MIPS: If we don't need DDR for cache init, init cache firstPaul Burton2016-09-21-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems where cache initialisation doesn't require zeroed memory (ie. systems where CONFIG_SYS_MIPS_CACHE_INIT_RAM_LOAD is not defined) perform cache initialisation prior to lowlevel_init & DDR initialisation. This allows for DDR initialisation code to run cached & thus significantly faster. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | MIPS: Preserve Config implementation-defined bitsPaul Burton2016-09-21-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The coprocessor 0 Config register includes 9 implementation defined bits, which in some processors do things like enable write combining or other functionality. We ought not to wipe them to 0 during boot. Rather than doing so, preserve their value & only clear the bits standardised by the MIPS architecture. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * | MIPS: Enable use of the instruction cache earlierPaul Burton2016-09-21-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Enable use of the instruction cache immediately after it has been initialised. This will only take effect if U-Boot was linked to run from kseg0 rather than kseg1, but when this is the case the data cache initialisation code will run cached & thus significantly faster.

| * | MIPS: Probe cache line sizes once during bootPaul Burton2016-09-21-18/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than probing the cache line sizes on every call of any cache maintenance function, probe them once during boot & store the values in the global data structure for later use. This will reduce the overhead of the cache maintenance functions, which isn't a big deal yet but becomes more important once L2 caches which may expose their properties via coprocessor 2 or the CM are supported.
