2014-07-28ARM: 7670/1: fix the memset fixNicolas Pitre
Commit 455bd4c430b0 ("ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) optimizations") attempted to fix a compliance issue with the memset return value. However the memset itself became broken by that patch for misaligned pointers. This fixes the above by branching over the entry code from the misaligned fixup code to avoid reloading the original pointer. Also, because the function entry alignment is wrong in the Thumb mode compilation, that fixup code is moved to the end. While at it, the entry instructions are slightly reworked to help dual issue pipelines.

2014-07-28ARM: 7668/1: fix memset-related crashes caused by recent GCC (4.7.2) ↵Ivan Djelic
optimizations Recent GCC versions (e.g. GCC-4.7.2) perform optimizations based on assumptions about the implementation of memset and similar functions. The current ARM optimized memset code does not return the value of its first argument, as is usually expected from standard implementations. For instance in the following function: void debug_mutex_lock_common(struct mutex *lock, struct mutex_waiter *waiter) { memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter)); waiter->magic = waiter; INIT_LIST_HEAD(&waiter->list); } compiled as: 800554d0 <debug_mutex_lock_common>: 800554d0: e92d4008 push {r3, lr} 800554d4: e1a00001 mov r0, r1 800554d8: e3a02010 mov r2, #16 ; 0x10 800554dc: e3a01011 mov r1, #17 ; 0x11 800554e0: eb04426e bl 80165ea0 <memset> 800554e4: e1a03000 mov r3, r0 800554e8: e583000c str r0, [r3, #12] 800554ec: e5830000 str r0, [r3] 800554f0: e5830004 str r0, [r3, #4] 800554f4: e8bd8008 pop {r3, pc} GCC assumes memset returns the value of pointer 'waiter' in register r0; causing register/memory corruptions. This patch fixes the return value of the assembly version of memset. It adds a 'mov' instruction and merges an additional load+store into existing load/store instructions. For ease of review, here is a breakdown of the patch into 4 simple steps: Step 1 ====== Perform the following substitutions: ip -> r8, then r0 -> ip, and insert 'mov ip, r0' as the first statement of the function. At this point, we have a memset() implementation returning the proper result, but corrupting r8 on some paths (the ones that were using ip). Step 2 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 1: save r8: - str lr, [sp, #-4]! + stmfd sp!, {r8, lr} and restore r8 on both exit paths: - ldmeqfd sp!, {pc} @ Now <64 bytes to go. + ldmeqfd sp!, {r8, pc} @ Now <64 bytes to go. (...) tst r2, #16 stmneia ip!, {r1, r3, r8, lr} - ldr lr, [sp], #4 + ldmfd sp!, {r8, lr} Step 3 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 0: save r8: - stmfd sp!, {r4-r7, lr} + stmfd sp!, {r4-r8, lr} and restore r8 on both exit paths: bgt 3b - ldmeqfd sp!, {r4-r7, pc} + ldmeqfd sp!, {r4-r8, pc} (...) tst r2, #16 stmneia ip!, {r4-r7} - ldmfd sp!, {r4-r7, lr} + ldmfd sp!, {r4-r8, lr} Step 4 ====== Rewrite register list "r4-r7, r8" as "r4-r8".

2014-07-26apalis/colibri t20/t30: enable vlan functionalityMarcel Ziswiler
Enable VLAN networking functionality. While at it also enable some more kernel modules for Apalis T30 PCIe based devices like the Intel E1000E NICs, Intel IWLAGN Wi-Fi cards, PCIe serial cards and XHCI based USB 3.0 controllers.
2014-07-25apalis/colibri t30: use hda hdmi audio and split sound initMarcel Ziswiler
Use HDA HDMI audio now on Colibri T30 as well allowing for up to 7.1 multi-channel playback. Split board sound initialisation between Apalis and Colibri T30 in order to distinguish better between default SPDIF being supported out-of-the-box on Apalis vs. this being an optional feature for the Colibri. Therefore remove SPDIF for the Colibri T30. While at it add csus clock required for vi_sensor camera master clock on Apalis T30 and clk_out_2/extern2 for Colibri T30, fix debug UART1 initialisation, get rid of spurious CONFIG_SND_USB enable and further clean-up both board platform data files.

Enable CONFIG_FHANDLE required for systemd >= 209 according to lists.freedesktop.org/archives/systemd-devel/2014-February/017362.html While at it put them all 3 on par concerning ARM Errata configuration.
2014-07-22apalis/colibri t20/t30: fix/introduce spi device controller dataMarcel Ziswiler
Fix (Colibri) resp. introduce (Apalis) SPI device controller data to properly use HW based chip select with one clock of setup and hold time each for both MCP2515 CAN controller(s) as well as spidev.
2014-07-21mmc: tegra: use 1.8V quirk only on affected instancesStefan Agner
The 1.8V quirk also affected the internal eMMC which disabled newer modes such as SDR50, SDR104 and DDR50. This in turn lead to an out of spec usage since the clock was still 50MHz. By creating a no_1v8 field in the platform data we can now enable this work around on a per-instance basis. Hence we enable the quirk only on the controllers which are connected to the external SD-slots.

2014-05-09colibri t20/t30: add spi controller platform data for hw csMarcel Ziswiler
Add SPI controller platform data required for use of hardware chip selects. While at it pull-up SPI chip select pin due to NVIDIA's designers taking the term chip select a little too personal: they indeed only select a chip otherwise all the chip select pins are just left floating!
2014-05-09colibri t20/t30: clarify mcp2515 resetMarcel Ziswiler
The MCP2515 on the Colibri EvalBoard V3.1a actually uses regular system reset aka RESET_OUT# on SODIMM 87 to reset the MCP2515. Therefore clean-up resp. remove any MECS Tellurium legacy in that respect. While at it adjust copyright year, re-order some include, clean-up some struct spacing, re-order clocks and improve some comments.
