2014-09-09arm: vf610: lpuart: disable FIFO on initializatonStefan Agner
UART does not use the UART FIFO, but we should also not rely that the UART FIFO is diabled by default. For instance, when loading U-Boot using the boot ROMs serial downloader protocol over UART, FIFO is enabled at U-Boot start time. This patch disables the RX and TX FIFO, sets back their thresholds and flushes them. Signed-off-by: Stefan Agner <stefan@agner.ch>
2014-09-09arm: vf610: lpuart: fix status register handlingStefan Agner
The status register 1 (S1) is not writeable, hence we should not write it. In order to clear the RDRF flag we only need to read the data register. Also, when stressing U-Boot a lot with serial input, an overflow can occur which asserts the S1_OR flag (while not asserting the S1_RDRF flag). To clear this flag we again just need to read the data register, hence add this flag to the abort conditions for the while loop. Insert a compiler barrier to make sure reading the data register gets executed after reading the status register. Signed-off-by: Stefan Agner <stefan@agner.ch>

2014-09-09net: fec_mxc: Poll FEC_TBD_READY after polling TDARFabio Estevam
When testing the FEC driver on a mx6solox we noticed that the TDAR bit gets always cleared prior then the READY bit is cleared in the last BD, which causes FEC packets reception to always fail. As explained by Ye Li: "The TDAR bit is cleared when the descriptors are all out from TX ring, but on mx6solox we noticed that the READY bit is still not cleared right after TDAR. These are two distinct signals, and in IC simulation, we found that TDAR always gets cleared prior than the READY bit of last BD becomes cleared. In mx6solox, we use a later version of FEC IP. It looks like that this intrinsic behaviour of TDAR bit has changed in this newer FEC version." Fix this by polling the READY bit of BD after the TDAR polling, which covers the mx6solox case and does not harm the other SoCs. No performance drop has been noticed with this patch applied when testing TFTP transfers on several boards of different i.mx SoCs.

2014-09-09net: fec_mxc: Adjust RX DMA alignment for mx6soloxFabio Estevam
mx6solox has a requirement for 64 bytes alignment for RX DMA transfer. Other SoCs work with the standard 32 bytes alignment. Adjust it accordingly by using 64 bytes aligment in the FEC RX DMA buffers, which addresses the needs from mx6solox and also works for the other SoCs.

2014-09-04mtd: nand: omap_gpmc: Fix 'bit-flip' errorsRostislav Lisovy
OMAP GPMC driver used with some NAND Flash devices (e.g. Spansion S34ML08G1) causes that U-boot shows hundreds of 'nand: bit-flip corrected' error messages. Possible cause was discussed in the mailinglist thread: http://lists.denx.de/pipermail/u-boot/2014-April/177508.html Quote (Author: Pekon Gupta <pekon@ti.com>): "The issue is mainly due to a NAND protocol violation in the omap driver since the Random Data Output command (05h-E0h) expects to see only the column address that should be addressed within the already loaded read page into the read buffer. Only 2 address cycles with ALE active should be provided between the 05h and E0h commands. The Page read command expects the full address footprint (2bytes for column address + 3bytes for row address), but once the page is loaded into the read buffer, Random Data Output should be used with only 2bytes for column address." This patch combines the solution proposed in the mailinglist and the patch provided by the Spansion company (GPLv2 code, source: http://www.spansion.com/Support/Software/u-boot-psp-04.04.00.01-NAND.zip) Signed-off-by: Rostislav Lisovy <lisovy@merica.cz>

2014-09-02dfu: Provide means to find difference between dfu-util -e and -RLukasz Majewski
This commit provides distinction between DFU device detach and reset. The -R behavior is preserved with proper handling of the dfu-util's -e switch, which detach the DFU device. By running dfu-util -e; one can force device to finish the execution of dfu command on target and execute some other scripted commands. Moreover, some naming has been changed - the dfu_reset() method now is known as dfu_detach(). New name better reflects the purpose of the code. It was also necessary to increase the number of usb_gadget_handle_interrupts() calls since we also must wait for detection of the USB reset event. Example usage: 1. -e (detach) switch dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e access to u-boot prompt. 2. -R (reset) switch dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage target board reset Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Tested-by: Stephen Warren <swarren@nvidia.com>

2014-08-28net: cpsw: am335x: Drop constant link checking from rx/tx path'sStefan Roese
We noticed on the DXR2 platform (AM335x with a SMSC LAN9303 switch connected to the CPSW MAC) that the network performance in U-Boot is quite poor. Only when the transfer is started without a cable connected, and the cable is plugged after the first timeout "T" occured, an increased in performance can be seen. Debugging has revealed, that the cpsw driver has constant link checking builtin into the rx and tx functions. This results in the bad performance and seems to be unnecessary. The link has already been checked in the init function, before the transfer is started. This usually is sufficient. BTW: I have seen no other network driver in U-Boot so far, that constantly checks for link in the rx / tx functions. The performance numbers on the DXR2 board are: 0.56 MiB/s cpsw_check_link() in rx and tx path 0.87 MiB/s cpsw_check_link() only in tx path 1.0 MiB/s cpsw_check_link() only in rx path 2.7 MiB/s no cpsw_check_link() in rx and tx path So with this patch the network performance on DXR2 increases from 0.56 to 2.7 MiB/s (nearly 5 times as fast).

2014-08-20powerpc/T4240QDS/eth: some fix for XFIShaohui Xie
XFI is supported on T4QDS-XFI board, which removed slot3, and four LANEs of serdes2 are routed to a SFP+ cages, which to house fiber cable or direct attach cable(copper), the copper cable is used to emulate the 10GBASE-KR scenario. So, for XFI usage, there are two scenarios, one will use fiber cable, another will use copper cable. For fiber cable, there is NO PHY, while for copper cable, we need to use internal PHY which exist in Serdes to do auto-negotiation and link training, which implemented in kernel. We use hwconfig to define cable type for XFI, and fixup dtb based on the cable type. For copper cable, set below env in hwconfig: fsl_10gkr_copper:<10g_mac_name> the <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2. The four <10g_mac_name>s do not have to be coexist in hwconfig. For XFI ports, if a given 10G port will use the copper cable for 10GBASE-KR, set the <10g_mac_name> of the port in hwconfig, otherwise, fiber cable will be assumed to be used for the port. For ex. if four XFI ports will both use copper cable, the hwconfig should contain: fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2 For fiber cable: 1. give PHY address to a XFI port, otherwise, the XFI ports will not be available in U-boot, there is no PHY physically for XFI when using fiber cable, this is just to make U-boot happy and we can use the XFI ports in U-boot. 2. fixup dtb to use fixed-link in case of fiber cable which has no PHY. Kernel requests that a MAC must have a PHY or fixed-link. When using XFI protocol, the MAC 9/10 on FM1 should init as 10G interface. Change serdes 2 protocol 56 to 55 which has same feature as 56 since 56 is not valid any longer. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
