2013-05-05mtd: nand: add driver for diskonchip g4 nand flashMike Dunn
This patch adds a driver for the diskonchip G4 nand flash device. It is based on the driver from the linux kernel. This also includes a separate SPL driver. A separate SPL driver is used because the device operates in a different mode (reliable mode) when loading a boot image, and also because the storage format of the boot image is different from normal data (pages are stored redundantly). The SPL driver basically mimics how a typical IPL reads data from the device. The special operating mode and storage format are used to compensate for the fact that the IPL does not contain the BCH ecc decoding algorithm (due to size constraints). Although the u-boot SPL *could* use ecc, it operates like an IPL for the sake of simplicity and uniformity, since the IPL and SPL share the task of loading the u-boot image. As a side benefit, the SPL driver is very small. [port from linux kernel 3.4 commit 570469f3bde7f71cc1ece07a18d54a05b6a8775d] Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
2013-05-05lib: import bitrev library from the linux kernelMike Dunn
This patch adds the bitrev library from the linux kernel. This is a simple algorithm that uses an 8 bit look-up table to reverse the bits in data types of 8, 16, or 32 bit widths. The docg4 nand flash driver uses it. [port from linux kernel v3.9 commit 7ee32a6d30d1c8a3b7a07a6269da8f0a08662927] [originally added: v2.6.20 by commit a5cfc1ec58a07074dacb6aa8c79eff864c966d12] Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
2013-04-01Consolidate bool typeYork Sun
'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun <yorksun@freescale.com>
2012-12-13Make linux kernel string funcs available to toolsJoe Hershberger
isspace() and strim() are not in the typical user-mode string.h, so put them in a separate compilation unit so that they can be built into tools that need them independent of the other common string functions. This allows code shared by u-boot and the linux user-mode tools to link. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-11Add strcasecmp() and strncasecmp()Simon Glass
strncasecmp() is present as strnicmp() but disabled. Make it available and define strcasecmp() also. There is a only a small performance penalty to having strcasecmp() call strncasecmp(), so do this instead of a standalone function, to save code space. Update the prototype in arch-specific headers as needed to avoid warnings. Signed-off-by: Simon Glass <sjg@chromium.org>

2012-11-20musb-new: port of Linux musb driverIlya Yanok
Existing U-Boot musb driver has no support for the new gadget framework and also seems to have other limitations. As gadget framework is ported from Linux it seems pretty natural to port musb gadget driver as well. This driver supports both host and peripheral modes. This is not a replacement for current musb driver (at least now) as there are still some consumers of the old UDC interface. No DMA operation support included, CONFIG_MUSB_PIO_ONLY should be defined. Virtual root hub device is not implemented. Known problems: with no devices connected usb_lowlevel_start() fails. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>

u-boot's byteorder headers did not contain endianness attributions for use with sparse, causing a lot of false positives.

2012-09-17mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driverMarek Vasut
This is based on Linux kernel -next: commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b Author: Brian Norris <computersforpeace@gmail.com> Date: Fri Jul 13 09:28:24 2012 -0700 mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.

2011-04-20Create PHY Lib for U-BootAndy Fleming
Extends the mii_dev structure to participate in a full-blown MDIO and PHY driver scheme. The mii_dev structure and miiphy calls are modified in such a way to allow the original mii command and miiphy infrastructure to work as before, but also to support a new set of APIs which allow (among other things) sharing of PHY driver code and 10G support The mii command will continue to support normal PHY management functions (Clause 22 of 802.3), but will not be changed to support 10G (Clause 45). The basic design is similar to PHY Lib from Linux, but simplified for U-Boot's network and driver infrastructure. We now have MDIO drivers and PHY drivers An MDIO driver provides: read write reset A PHY driver provides: (optionally): probe config - initial setup, starting of auto-negotiation startup - waiting for AN, and reading link state shutdown - any cleanup needed The ethernet drivers interact with the PHY Lib using these functions: phy_connect() phy_config() phy_startup() phy_shutdown() Each PHY driver can be configured separately, or all at once using config_phylib_all_drivers.h (added in the patch which adds the drivers) We also provide generic drivers for Clause 22 (10/100/1000), and Clause 45 (10G) PHYs. We also implement phy_reset(), and call it in phy_connect(). Because phy_reset() is essentially the same as miiphy_reset, but: a) must support 10G PHYs, and b) should use the phylib primitives, we implement miiphy_reset, using phy_reset(), but only when CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this way, we save on compile size, even if we don't manage to save code size.

2011-04-01NAND: add support for reading ONFI page tableFlorian Fainelli
This patch adds support for reading an ONFI page parameter from a NAND device supporting it. If this is the case, struct nand_chip onfi_version member contains the supported ONFI version, 0 otherwise. This allows NAND drivers past nand_scan_ident to set the best timings for the NAND chip.
