| | | | | | | | | | | | | | | | | | | | To prepare timer driver to DM/DT conversion do not build the exiting timer driver when CONFIG_TIMER is defined. But since omap's SPL doesn't support DM yet so built timer driver only for SPL build when CONFIG_TIMER is defined.

* arm: lpc32xx: switch SPL builds to driver modelVladimir Zapolskiy2016-01-131-1/+1
| | | | | | | | | | | | | | | | For NXP LPC32xx boards the change enables SPL_DM option, this allows to use any driver model UART driver in SPL images, hence a restriction on HSUART in SPL image is removed and well as definitions for non-DM NS16550 driver, its DM version is used instead. Because SPL_DM requires malloc(), enable CONFIG_SPL_SYS_MALLOC_SIMPLE for LPC32xx boards. The change adds about 5KB to the resulting SPL image (for devkit3250 board SPL image is increased from 10672 to 15608 bytes).

| | | | | | | | | | | | | | | | | On NXP LPC32xx platform for non-SPL builds the change adds standard (NS16550) and high-speed UARTs to driver model. Due to specific of DM NS16550 device description UART clock can not be got in runtime and by default it is set to 13MHz, if board PERIPH_CLK is different, this should be specified in board configuration file. For SPL builds HSUARTs are disabled and non-DM NS16550 driver is compiled, if needed. The change also updates default configs of devkit3250 and work_92105 boards to reflect updates in platform files.

Non-secure master such as SDHC DMA cannot access data correctly. Mixing secure and non- secure MMU entries requirs the MMU tables themselves in secure memory. This patch moves MMU tables into a secure DDR area. Early MMU tables are changed to set DDR as non-secure. A new table is added into final MMU tables so secure memory can have 2MB granuality. gd->secure_ram tracks the location of this secure memory. For ARMv8 SoCs, the RAM base is not zero and RAM is divided into several banks. gd->secure_ram needs to be maintained before using. This maintenance is board-specific, depending on the SoC and memory bank of the secure memory falls into. Signed-off-by: York Sun <yorksun@freescale.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment, the desired brownout is at 1.0V. However, this setting cannot be realized by hardware since we have only 3 bits to represent the voltage difference from the target value. Target value is 1500 mV, brownout target is 1000 mV, voltage steps are 25 mV. Register content calculation: (1500 [mV] - 1000 [mV]) / 25 [mV] = 20 (decimal) = 0x14 Register takes only 3 bits, that is 0x4. But 0x4 * 25 [mV] = 100 [mV], that means that actual brownout level is 1500 [mV] - 100 [mV] = 1.4 V. Minimum possible BO level is 1500 [mV] - 0x7 * 25 [mV] = 1315 [mV]. So lets use this value as desired BO value (which is also the same as FSL bootlets use).
