* MLK-10176-6 imx: mx7: Modify GPT timer driver for mx7Peng Fan2017-04-05-2/+8
| | | | | | | | | | | | | Modify the GPT common platform driver for mx7 which only use 24Mhz OSC as clock source. Note: at default, the mx7d will use system counter as timer. The GPT is disabled.

* arm: imx-common: introduce back usec2ticksPeng Fan2016-10-17-0/+16
| | | | | | | | | | | | | | This commit "2bb014820c49a63902103bac710bc86b5772e843" do some clean up to use the code in lib/time.c. But usec2ticks is still being used by security related job ring code. Bring back the function to avoid build break when CONFIG_FSL_CAAM is defined. The computation logic has been changed, using 64-bit variable to ease the process, making it work on older (MX5) platforms.

* imx-common: timer: clean up codePeng Fan2015-10-30-73/+2
| | | | | | | | | | | We can reuse common functions in lib/time.c, but not reimplement functions in imx-common/time.c. Only keep timer_init ,get_tbclk and implement timer_read_counter in imx-common/time.c.

* imx6: Added DEK blob generator commandRaul Cardenas2015-03-02-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freescale's SEC block has built-in Data Encryption Key(DEK) Blob Protocol which provides a method for protecting a DEK for non-secure memory storage. SEC block protects data in a data structure called a Secret Key Blob, which provides both confidentiality and integrity protection. Every time the blob encapsulation is executed, a AES-256 key is randomly generated to encrypt the DEK. This key is encrypted with the OTP Secret key from SoC. The resulting blob consists of the encrypted AES-256 key, the encrypted DEK, and a 16-bit MAC. During decapsulation, the reverse process is performed to get back the original DEK. A caveat to the blob decapsulation process, is that the DEK is decrypted in secure-memory and can only be read by FSL SEC HW. The DEK is used to decrypt data during encrypted boot. Commands added -------------- dek_blob - encapsulating DEK as a cryptgraphic blob Commands Syntax --------------- dek_blob src dst len Encapsulate and create blob of a len-bits DEK at address src and store the result at address dst.

* imx: gpt: Add High frequency clock source support for GPTYe.Li2014-11-03-9/+66
| | | | | | | | | | | | | | | | | Introduce a new configuration "CONFIG_MXC_GPT_HCLK". When it is set, the GPT will select a high frequency clock as clock source. Otherwise, the GPT will stay to use 32Khz OSC as clock source. In the implementation, since only the GPT on i.MX6 series provide the clock source option for 24Mhz OSC. For others (only i.MX5 and i.MX6 compile the driver), if the configuration is set, the perclk will be selected as clock source. MX6Q/D Rev 1.0 and MX6SL are special in the implementation, because they don't have the 24Mhz OSC clock source option, so also select the perclk for them. For MX6SL, we will set the OSC 24Mhz to perclk in CCM, so eventually the clock comes from OSC 24Mhz. Signed-off-by: Ye.Li <B37916@freescale.com>

* imx-common: timer: fix 32-bit overflowKnut Wohlrab2013-03-20-19/+7
| | | | | | | | | | | | | | | The i.MX6 common timer uses the 32-bit variable tbl (time base lower) to record the overflow of the 32-bit counter. I.e. if the counter overflows, the variable tbl does overflow, too. To capture this overflow, use the variable tbu (time base upper), too. Return the combined value of tbl and tbu. lastinc is unused then, remove it.

* MX: set a common place to share code for Freescale i.MXStefano Babic2012-09-10-0/+149
Up now only MX5 and MX6 can share code, because they have a common source directory in cpu/armv7. Other not armv7 i.MX can profit of the same shared code. Move these files into a directory accessible for all, similar to plat-mxc in linux. Signed-off-by: Stefano Babic <sbabic@denx.de>
