* usb:udc:samsung: Zero copy approach for data passed to Samsung's UDC driverLukasz Majewski2014-02-06-44/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | The Samsung's UDC driver is not anymore copying data from USB requests to aligned internal buffers. Now it works directly in data allocated in the upper layers like UMS, DFU, THOR. This change is possible since those gadgets now must take care to allocate buffers aligned to cache line (CONFIG_SYS_CACHELINE_SIZE). This can be achieved by using DEFINE_CACHE_ALIGN_BUFFER() or ALLOC_CACHE_ALIGN_BUFFER() macros. Those take care to allocate buffer aligned to cache line in both starting address and its size. Sometimes it is enough to just use memalign() with size being a multiplication of cache line size.

* usb:udc:samsung: Allow burst transfers for non EP0 endpintsLukasz Majewski2014-02-06-4/+3
| | | | | | | | | | | | | | | | | | | This patch removed obscure restriction on the HW setting of DMA transfers. Before this change each transaction sent up to 512 bytes (with packet count equal to 1) for non EP0 transfer. Now it is possible to setup DMA transaction up to DMA_BUFFER_SIZE.

* usb:udc:samsung: Remove redundant cache operation from Samsung UDC driverLukasz Majewski2014-02-06-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A set of cache operations (both invalidation and flush) were redundant in the S3C HS OTG Samsung driver: 1. s3c_udc_ep0_zlp - to transmit EP0's ZLP packets one don't need to flush the cache (since it is the zero length transmission) 2. s3c_udc_pre_setup and s3c_ep0_complete_out - cache invalidation is not needed when the buffer for OUT EP0 transmission is setup, since no data has yet arrived. Cache cleanups presented above don't contribute much to transmission speed up, hence shall be regarded as cosmetic changes. 3. setdma_rx - here the s3c UDC driver's internal buffers were invalidated. This call is not needed anymore since we reuse the buffers passed from gadgets. This is a key contribution to transmission speed improvement.

| * | | kmp204x: initial support for PCIe FPGA configurationValentin Longchamp2014-02-03-1/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PEXHC PCIe configuration mechanism ensures that the FPGA get configured at power-up. Since all the PCIe devices should be configured when the kernel start, u-boot has to take care that the FPGA gets configured also in other reset scenarios, mostly because of possible configuration change. The used mechanism is taken from the km_kirkwood design and adapted to the kmp204x case (slightly different HW and PCIe configuration).

* | board_r - fixup functions table after relocationAlexey Brodkin2014-01-27-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is only required for "PIC" relocation and doesn't apply to modern "PIE" relocation which does data relocation as well as code. "init_sequence_r" is just an array that consists of compile-time adresses of init functions. Since this is basically an array of integers (pointers to "void" to be more precise) it won't be modified during relocation - it will be just copied to new location as it is. As a consequence on execution after relocation "initcall_run_list" will be jumping to pre-relocation addresses. As long as we don't overwrite pre-relocation memory area init calls are executed correctly. But still it is dangerous because after relocation we don't expect initially used memory to stay untouched.
