* tpm: Add TPM stress testLuigi Semenzato2012-12-11-6/+87
| | | | | | | | Add a simple command to stress-test a TPM (Trusted Platform Module). Signed-off-by: Luigi Semenzato <semenzato@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* console: Enable function to display console infoSimon Glass2012-12-11-2/+4
| | | | | | | | | | | The CONFIG_SYS_CONSOLE_INFO_QUIET option should suppress the console information, but allow boards to display it later if required. Adjust the code to support this. This is used to avoid printing the information while the LCD display is not ready, since it only becomes ready when stdio init is complete. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add console command to access io space registersVadim Bendebury2012-12-11-4/+99
| | | | | | | | | | | | | | | | | | | Provide u-boot console functions to access IO space registers. A no thrills implementation, accessing one register at a time. For example: boot > iod 80 0080: 00000094 boot > iod.w 80 0080: 0094 boot > iod.b 80 0080: 94 boot > iow.b 0x80 12 boot > iod 0x80 0080: 00000012 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* edid: Add I2C command for printing the EDIDTom Wai-Hong Tam2012-12-11-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a single command to read the EDID information over I2C. For example: SMDK5250 # i2c dev 7 Setting bus to 7 SMDK5250 # i2c edid 50 EDID version: 1.4 Product ID code: 305c Manufacturer: AUO Serial number: 00000000 Manufactured in week: 0 year: 2011 Video input definition: digital signal, voltage level 0, blank to black Monitor is non-RGB Maximum visible display size: 26 cm x 14 cm Power management features: no active off, no suspend, no standby Estabilished timings: Standard timings: 1366x768 60 Hz (detailed) 1366x768 60 Hz (detailed) Monitor ID: 2VD2K.B116XW Signed-off-by: Tom Wai-Hong Tam <waihong@chromium.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* edid: Library of EDID decode and printTom Wai-Hong Tam2012-12-11-0/+583
| | | | | | | | | | | | | | | | | | | This implements a library for accessing EDID data from an LCD panel. This is used to obtain information about the panel such as its resolution and type. This is a tidied-up version of the original code pulled from https://github.com/ynezz/u-boot-edid. The changes we made are: - removed bit fields in the struct; - removed endianness cases in the struct; - fixed some wrong definitions; - fixed to fit 80 columns; - fixed some code styles.

* Add hash command to perform hashing using various algorithmsSimon Glass2012-12-11-0/+83
| | | | | | | | | | | | | | | | | | | | | This new command supports hashing SHA1 and SHA256. It could be extended to others such as MD5 and the CRC algorithms. The syntax is modeled on those: hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>] to calculate a hash, and: hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>] to verify a hash. Use CONFIG_CMD_HASH to enable the command, CONFIG_SHA1 to enable SHA1 and CONFIG_SHA256 to enable SHA256. The existing sha1sum command remains. Signed-off-by: Simon Glass <sjg@chromium.org>
* sha1sum: Use generic hash layerSimon Glass2012-12-11-125/+4
| | | | | | Update the code to use the hash layer instead of local code. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add generic hash APISimon Glass2012-12-11-0/+291
| | | | | | | | We have a SHA1 command and want to add a SHA256 command also. Instead of duplicating the code, create a generic hash API which can process commands for different algorithms. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add strcasecmp() and strncasecmp()Simon Glass2012-12-11-9/+20
| | | | | | | | | | | 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>
* sha256: Use const where possible and add watchdog functionSimon Glass2012-12-11-3/+42
| | | | | | | | | In preparation for making the hash function common, we may as well use const where we can. Also add a watchdog version of the hashing function. Signed-off-by: Simon Glass <sjg@chromium.org>
* sha1: Use const where possible, and unsigned for input lenSimon Glass2012-12-11-25/+20
| | | | | | | | In preparation for making the hash function common, we may as well use const where we can. Also the input length cannot be negative, but may be very large, so use unsigned. Signed-off-by: Simon Glass <sjg@chromium.org>
* stdio: remove useless strncpyVincent Palatin2012-12-11-1/+0
| | | | | | | | | | | | | | The name is already copied when we memcpy() the whole structure. This is because struct stdio_dev has this field: char name[16]; /* Device name */ So the data is inline, rather than being a pointer.

* Fix use of conditional LMBSimon Glass2012-12-11-1/+1
| | | | | | This code was not guarded with CONFIG_LMB so failed to build on x86. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add a command to read raw blocks from a partitionKenneth Waters2012-12-11-0/+84
| | | | | | | | | | Sometimes data is on a block device and within a partition, but not in a particular filesystem. This commands permits reading raw data from a partition. Signed-off-by: Kenneth Waters <kwaters@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* Add gettime commandAnton Staaf2012-12-11-0/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Gettime returns the current timer value. If CONFIG_SYS_HZ is defined then the timer value is also converted to seconds. Tegra20 (SeaBoard) # gettime Timer val: 7754 Seconds : 7 Remainder : 754 sys_hz = 1000 There has been some discussion about whether this is useful enough to be included in U-Boot. The following boards do not have CONFIG_SYS_HZ defined: M52277EVB M52277EVB_stmicro M53017EVB M54418TWR M54418TWR_nand_mii M54418TWR_nand_rmii M54418TWR_nand_rmii_lowfreq M54418TWR_serial_mii M54418TWR_serial_rmii Signed-off-by: Anton Staaf <robotboy@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* designware_i2c: Fixed the setting of the i2c bus speedArmando Visconti2012-12-11-15/+13
| | | | | | | | There are three couple (hcnt/lcnt) of registers for each speed (SS/FS/HS). The driver needs to set the proper couple of regs according to what speed we are setting. Signed-off-by: Armando Visconti <armando.visconti@st.com>
* designware_i2c: Added s/w generation of stop bitArmando Visconti2012-12-11-3/+9
| | | | | | | | | | | | | | | In the newer versions of designware i2c IP there is the possibility of configuring it with IC_EMPTYFIFO_HOLD_MASTER_EN=1, which basically requires the s/w to generate the stop bit condition directly, as the h/w will not automatically generate it when TX_FIFO is empty. To avoid generation of an extra 0x0 byte sent as data, the IC_STOP command must be sent along with the last IC_CMD. This patch always writes bit[9] of ic_data_cmd even in the older versions, assuming that it is a noop there. Signed-off-by: Armando Visconti <armando.visconti@st.com>

| | | | | | | | | | | OMAP5 has 8b i2c data register field, like OMAP2, 3 and 4. Handle in the same way. This fixes the following error on OMAP5: OMAP5430 EVM # mmc rescan timed out in wait_for_bb: I2C_STAT=1410 twl6035: could not turn on LDO9. Signed-off-by: Vincent Stehlé <v-stehle@ti.com>
* mxs: i2c: Implement algorithm to set up arbitrary i2c speedMarek Vasut2012-12-11-53/+37
| | | | | | | | | | | | | | | This algorithm computes the values of TIMING{0,1,2} registers for the MX28 I2C block. This algorithm was derived by using a scope, but the result seems correct. The resulting values programmed into the registers do not correlate with the contents in datasheet. When using the values from the datasheet, the I2C clock were completely wrong.

* mxs: i2c: Restore speed setting after block resetMarek Vasut2012-12-11-0/+3
| | | | | | | | | | | | The I2C block reset configures the I2C bus speed to strange value. Read the I2C speed from the block before reseting the block and restore it afterwards, so the I2C operates correctly. This issue can be replicated by doing unsuccessful I2C transfer, after such transfer finishes, the I2C block clock speed is misconfigured.

* i2c: mxs: Fix TIMING2 register valueMarek Vasut2012-12-11-2/+2
| | | | | | | | | | | According to FSL, the value in the TIMING2 register shall be 0x00300030 instead of what's written in the datasheet. This new value correlates with older STMP36xx datasheet. Issues were detected in Linux when this register was misconfigured, so write this correct value.
