| | | | | | | | | | | | | | | | | | | | | | Fastest read command code look for fastest read command taking inputs from spi->mode_rx and flags from param table and controller mode_rx is always been a priority. Since mode_rx is always set from controller side this optimized code doesn't require much and this code required exctra overhead like 1) Maintain e_rx_cmd in param table 2) Maintain mode_rx in spi_slave {} Hence removed this code, and look for read command from normal spi->mode from spi_slave{} and params->flags Cc: Simon Glass <sjg@chromium.org> Cc: Bin Meng <bmeng.cn@gmail.com> Cc: Michal Simek <michal.simek@xilinx.com> Cc: Siva Durga Prasad Paladugu <sivadur@xilinx.com> Cc: Vignesh R <vigneshr@ti.com> Cc: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: Jagan Teki <jteki@openedev.com>

* spi: ti_qspi: use 128 bit transfer mode when writing to flashVignesh R2016-09-22-6/+33
| | | | | | | | | | | | | | | | | | | | TI QSPI has four 32 bit data registers which can be used to transfer 16 bytes of data at once. The register group QSPI_SPI_DATA_REG_3, QSPI_SPI_DATA_REG_2, QSPI_SPI_DATA_REG_1 and QSPI_SPI_DATA_REG is treated as a single 128-bit word for shifting data in and out. The bit at QSPI_SPI_DATA_REG_3[31] position is the first bit to be shifted out in case of 128 bit transfer mode. Therefore the first byte to be written to flash should be at QSPI_SPI_DATA_REG_3[31-25] position. Instead of writing 1 byte at a time when interacting with SPI NOR flash, make use of all the four registers so that 16 bytes can be transferred in one go. With this patch, the flash write speed increases from ~250KBs/ to ~650KB/s on DRA74 EVM.

* Revert "Increase default of CONFIG_SYS_MALLOC_F_LEN for SPL_OF_CONTROL"Masahiro Yamada2016-09-19-1/+24
| | | | | | | | | | | | | | This reverts commit 90c08d9e08c7a108ab904f3bbdeb558081757892. I took a closer look at this after the commit was applied, and found CONFIG_SYS_MALLOC_F_LEN=0x2000 was too much. 8KB memory for SPL is actually too big for some boards. Perhaps 0x800 is enough, but the situation varies board by board. Let's postpone our decision until we come up with a better idea.

To avoid leaking the struct musb allocated by musb_init_controller() on repeated musb_usb_probe() calls, we were caching its result. But musb_init_controller() does more, such as calling sunxi_musb_init() which enables the clocks. Not calling sunxi_musb_init() causes the musb controller to stop working after a "usb reset" since that calls musb_usb_remove() which disables the clocks. This commit fixes this by removing the caching of the struct returned from musb_init_controller(), it replaces this by free-ing the allocated memory in musb_usb_remove() and calling musb_usb_remove() on musb_usb_probe() errors to ensure proper cleanup. While at it also make musb_usb_probe() and musb_usb_remove() static. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
