* ARC: Cache: Remove per-line I$ operations as unusedEugeniy Paltsev2018-03-211-23/+7
| | | | | | | | | | | | __cache_line_loop() function was copied from Linux kernel where per-line instruction cache operations are really used. In U-Boot we use only entire I$ ops, so we can drop support of per-line I$ ops from __cache_line_loop() because __cache_line_loop() is never called with OP_INV_IC parameter.

* ARC: Cache: Move I$ entire operation to a separate functionEugeniy Paltsev2018-03-211-12/+19
| | | | | | | | | Move instruction cache entire operation to a separate function because we are planing to use it in other places like sync_icache_dcache_all(). Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
* arc: Fine-tune implementation of memory barriersAlexey Brodkin2018-03-211-4/+4
| | | | | | | | | | | | | | | We improve on 2 things: 1. Only ARC HS family has "dmb" instructions so do compile-time check for automatically defined macro __ARCHS__. Previous check for ARCv2 ISA was not good enough because ARC EM family is v2 ISA as well but still "dmb" instaruction is not supported in EM family. 2. Still if there's no dedicated instruction for memory barrier let's at least insert compile-time barrier to make sure compiler deosn't reorder critical memory operations.

* arc: Introduce a possibility to not relocate U-bootAlexey Brodkin2018-03-213-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Disabling relocation might be useful on ARC for 2 reasons: a) For advanced debugging with Synopsys proprietary MetaWare debugger which is capable of accessing much more specific hardware resources compared to gdb. For example it may show contents of L1 and L2 caches, internal states of some hardware blocks etc. But on the downside MetaWare debugger still cannot work with PIE. Even though that limitation could be work-arounded with change of ELF's header and stripping down all debug info but with it we won't have debug info for source-level debugging which is quite inconvenient. b) Some platforms which might benefit from usage of U-Boot basically don't have enough RAM to accommodate relocation of U-Boot so we keep code in flash and use as much of RAM as possible for more interesting things.

* arc: Eliminate unused code and data with GCC's garbage collectorAlexey Brodkin2018-03-211-1/+2
| | | | | | | | | | | | | | | | | Finally GCC's garbage collector works on ARC so let's use it. That's what I may see for HSDK: Before: text data bss dec hex filename 290153 10068 222616 522837 7fa55 u-boot After: text data bss dec hex filename 261999 9460 222360 493819 788fb u-boot Overall ~5% of memory footprint saved.

* arc: Don't halt slavesAlexey Brodkin2018-03-211-20/+0
| | | | | | | | | | | | | | | | | | This commit basically reverts two commits: 1. cf628f772ef2 ("arc: arcv1: Disable master/slave check") 2. 6cba327bd96f ("arcv2: Halt non-master cores") With mentioned commits in-place we experience more trouble than benefits. In case of SMP Linux kernel this is really required as we have all the cores running from the very beginning and then we need to allow master core to do some preparatory work while slaves are not getting in the way. In case of U-Boot we: a) Don't really run more than 1 core in parallel b) We may use whatever core for that Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
* arc: Get rid of handwritten string routinesAlexey Brodkin2018-03-219-666/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot is a bit special piese of software because it is being only executed once on power-on as compared to operating system for example. That's why we don't care much about performance optimizations instead we're more concerned about size. And up-to-date compilers might produce much smaller code compared to performance-optimized routines copy-pasted from the Linux kernel. Here's an example: ------------------------------->8-------------------------- --- size_asm_strings.txt +++ size_c_strings.txt @@ -1,2 +1,2 @@ text data bss dec hex filename - 121260 3784 3308 128352 1f560 u-boot + 120448 3784 3308 127540 1f234 u-boot ------------------------------->8-------------------------- See we were able to shave off ~800 bytes of .text section. Also usage of string routines implemented in C gives us an ability to support more HW flavors for free: generated instructions will match our target as long as correct compiler option is used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we use hardware with very small RAM (let's consider just a couple of hundreds of kB but not megabytes) it is not super convenient to lose 64kB for statically allocated bufer which most probably won't be used as big as it is. Typically we'll have much shorter data packages to excahnge and in the worst case longer packets will be split on separate transactions. For those corner-cases user will be able to set his buffer size of choice via USB_DWC2_BUFFER_SIZE option in menuconfig. By default we'll use 64 kB as it was hard-coeded before so existing users shouldn't be affected at all. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Marek Vasut <marex@denx.de>

This new OS type will be used for chain-loading to Linux via a TEE.

This image type "-T kernel -O tee" is differentiated from the existing IH_TYPE_TEE "-T tee" in that the IH_TYPE is installed by u-boot (flow control returns to u-boot) whereas for the new IH_OS_TEE control passes to the OPTEE firmware and the firmware chainloads onto Linux.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OPTEE is currently linked to a specific area of memory called the TrustZone DRAM. This patch adds a CONFIG entry for the default address of TrustZone DRAM that a board-port can over-ride. The region that U-Boot sets aside for the OPTEE run-time should be verified before attempting to hand off to the OPTEE run-time. Each board-port should carefully ensure that the TZDRAM address specified in the OPTEE build and the TZDRAM address specified in U-Boot match-up. Further patches will use TZDRAM address with other defines and variables to carry out a degree of automated verification in U-Boot prior to trying to boot an OPTEE image.

* | | optee: Add lib entries for sharing OPTEE code across portsBryan O'Donoghue2018-03-196-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds code to lib to enable sharing of useful OPTEE code between board-ports and architectures. The code on lib/optee/optee.c comes from the TI omap2 port. Eventually the OMAP2 code will be patched to include the shared code. The intention here is to add more useful OPTEE specific code as more functionality gets added.
