2014-07-22AHCI: Increase link timeout to 200msIan Campbell
In 73545f75b66d "ahci: wait longer for link" I increased the timeout to 40ms based on the observed behaviour of a WD disk on a Cubietruck. Since then Karsten Merker and myself have both observed timeouts with HGST disks (Karsten on Cubietruck, me on Cubieboard2). Increasing the timeout to ~175ms fixes this, so go to 200ms for a bit of headroom.

2014-07-22serial: ns16550: drop CONFIG_OMAP1610 from the special caseMasahiro Yamada
If CONFIG_OMAP1610 is defined, the code returning the fixed value (26) is enabled. But this case is covered by the following code. (CONFIG_SYS_NS16550_CLK + (gd->baudrate * (MODE_X_DIV / 2))) / (MODE_X_DIV * gd->baudrate) = (48000000 + (115200 * (16 / 2))) / (16 * 115200) = 48921600 / 1843200 = 26 The "#ifdef CONFIG_OMAP1610" was added by commit 6f21347d more than ten years ago. In those days, the divide-and-round was not used. I guess that is why this weird code was added here.

2014-07-06sunxi: Remove mmc DMA supportHans de Goede
The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the dma descriptors on the stack, and then exits while the dma transfer is in progress, so the dma engine is reading stack memory which at that point may be re-used. So far we've gotten away with this by luck, but recent u-boot changes have shifted the stack start address by 16 bytes, which combined with dma alignment now exposes this problem. Since we end up just busy waiting for the dma engine anyway, this commit fixes things by simply removing the dma code, resulting in smaller bug-free code.

2014-07-04gpio: spear_gpio: Fix gpio_set_value() implementationAxel Lin
In current gpio_set_value() implementation, it always sets the gpio control bit no matter the value argument is 0 or 1. Thus the GPIOs never set to low. This patch fixes this bug. The address bus is used as a mask on read/write operations, so that independent software drivers can set their GPIO bits without affecting any other pins in a single write operation. Thus we don't need a read-modify-write to update the register.

Adding support to load and start the Layerscape Management Complex (MC) firmware. First, the MC GCR register is set to 0 to reset all cores. MC firmware and DPL images are copied from their location in NOR flash to DDR. MC registers are updated with the location of these images. Deasserting the reset bit of MC GCR register releases core 0 to run. Core 1 will be released by MC firmware. Stop bits are not touched for this step. U-boot waits for MC until it boots up.

2014-07-03i2c: tegra: write clean data to TX FIFOStephen Warren
The Tegra I2C controller's TX FIFO contains 32-bit words. If the final FIFO entry of a transaction contains fewer than 4 bytes, the driver currently fills the unused FIFO bytes with uninitialized data. This can be confusing when reading back the FIFO content for debugging purposes. Solve this by explicitly initializing the variable containing FIFO data before filling it (partially) with data. With this change, send_recv_packets()'s loop's if (is_write) code mirrors the else (i.e. read) branch. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Yen Lin <yelin@nvidia.com>

A UDC's alloc_request method should zero out the newly allocated request. Ensure the Atmel driver does so.

2014-07-02usb: ci_udc: don't memalign() struct ci_req allocationsStephen Warren
struct ci_req is a purely software structure, and needs no specific memory alignment. Hence, allocate it with calloc() rather than memalign().

2014-07-02usb: ci_udc: remove controller.items arrayStephen Warren
There's no need to store an array of QTD pointers in the controller. Since the calculation is so simple, just have ci_get_qtd() perform it at run-time, rather than pre-calculating everything. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-07-02usb: ci_udc: fix items array size/stride calculationStephen Warren
2 QTDs are allocated for each EP. The current allocation scheme aligns the first QTD in each pair, but simply adds the struct size to calculate the second QTD's address. This will result in a non-cache-aligned addresss IF the system's ARCH_DMA_MINALIGN is not 32 bytes (i.e. the size of struct ept_queue_item). Similarly, the original ilist_ent_sz calculation aligned the value to ARCH_DMA_MINALIGN but didn't take the USB HW's 32-byte alignment requirement into account. This doesn't cause a practical issue unless ARCH_DMA_MINALIGN < 32 (which I suspect is quite unlikely), but we may as well fix the code to be explicit, so it's obviously completely correct. The new value of ILIST_ENT_SZ takes all alignment requirements into account, so we can simplify ci_{flush,invalidate}_qtd() by simply using that macro rather than calling roundup(). Similarly, the calculation of controller.items[i] can be simplified, since each QTD is evenly spaced at its individual alignment requirement, rather than each pair being aligned, and entries within the pair being spaced apart only by structure size.

2014-07-02usb: ci_udc: lift ilist size calculations to global scopeStephen Warren
This will allow functions other than ci_udc_probe() to make use of the constants in a future change. This in turn requires converting the const int variables to #defines, since the initialization of one global const int can't depend on the value of another const int; the compiler thinks it's non-constant if that dependency exists.

This will allow us to correctly align each QTD individually in the future, which may involve leaving a gap between the QTDs. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2014-07-02usb: ci_udc: fix ci_flush_{qh,qtd} calls in ci_udc_probe()Stephen Warren
ci_udc_probe() initializes a pair of QHs and QTDs for each EP. After each pair has been initialized, the pair is cache-flushed. The conversion from QH/QTD index [0..2*NUM_END_POINTS) to EP index [0..NUM_ENDPOINTS] is incorrect; it simply subtracts 1 (which yields the QH/QTD index of the first entry in the pair) rather than dividing by two (which scales the range). Fix this. On my system, this avoids cache debug prints due to requests to flush unaligned ranges. This is caused because the flush calls happen before the items[] array entries are initialized for all but EP0. Signed-off-by: Stephen Warren <swarren@nvidia.com>
