| * | | | ARM: i.MX8MQ: Don't use cpu_is_mx8mq() at core_initcall levelAndrey Smirnov2019-03-186-25/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since __imx_cpu_type won't be initialized until imx_init()@postcore_initcall is executed cpu_is_mx8mq() will only work correctly at core_initcall level so long as imx_cpu_type does not resolve into __imx_cpu_type. This is currently the case and imx8mq_init_syscnt_frequency() works as expected, but it probably won't be in the future. To avoid this problem introduce imx8mq_cpu_lowlevel_init() and do system counter frequency initialization there. Also convert all of the i.MX8MQ boards to use this new function.

| * | | | ARM: i.MX7: Make sure CNTFRQ is initialized early enoughAndrey Smirnov2019-03-183-35/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to make sure that CNTFRQ is initialized before corresponding clocksource driver tries to use it, otherwise we'll end up crashing due to division by zero. We can't convert imx7_timer_init() to be an initcall since it is an i.MX7 specific task, but CPU type information won't be availible until after imx_init() gets executed at postcore_initcall() level. To solve this move all of the necessary code to be a part of imx7_cpu_lowlevel_init(). Note, that original code both hardcoded frequency value to 8MHz as well as tried to write it to the first element of the frequency mode table which appears to be read-only on i.MX7. So while we are at it, simplify the code by adding set_cntfrq() implementation for ARMv7 and copy the code we already using for i.MX8MQ.

It also stops barebox from zapping invalid buffers. This causes issues when the console writing code tries to use the uninitialized, invalid console buffer. Therefore, allow barebox to zap invalid buffers, the kernel will do so anyway if it finds broken buffers during its initialization.

(2) mem_type=1 becomes the more self-explanatory "unbuffered" property.

Also fixed the double release of memory in case of failure. barebox 2018.12.0-00341-g23b28d33a-dirty #6 Fri Mar 15 09:20:25 MSK 2019 Board: Mega-Milas Informer i.MX6 detected i.MX6 Quad revision 1.2 i.MX reset reason POR (SRSR: 0x00000001) mdio_bus: miibus0: probed eth0: got preset MAC address: 50:2d:f4:07:71:0b nand: NAND device: Manufacturer ID: 0xec, Chip ID: 0xd3 (Samsung NAND 1GiB 3,3V 8-bit), 1024MiB, page size: 2048, OOB size: 64 Bad block table found at page 524224, version 0x01 Bad block table found at page 524160, version 0x01 m25p80 flash@00: n25q128a13 (16384 Kbytes) imx-usb 2184000.usb@2184000: USB EHCI 1.00 imx-usb 2184200.usb@2184200: USB EHCI 1.00 imx-esdhc 2198000.usdhc@2198000: registered as mmc2 imx-ipuv3 2400000.ipu@2400000: IPUv3H probed ERROR: /ldb/lvds-channel@0/display-timings/PH320240T: illegal timing specification in clock-frequency ERROR: /ldb/lvds-channel@0/display-timings/PH320240T: error reading timing properties ERROR: /ldb/lvds-channel@0: error in timing 1 ERROR: unable to handle NULL pointer dereference at address 0x00000013 pc : [<4fe05742>] lr : [<4fe05849>] sp : 4ffefa80 ip : ffffffff fp : 2fefe84c r10: 2ff656e8 r9 : 0000002c r8 : 2ff19630 r7 : 00000000 r6 : 0000004c r5 : 2ff65960 r4 : 00000007 r3 : 00000013 r2 : 00000000 r1 : 4fe87584 r0 : 2fefb460 Flags: nzcv IRQs off FIQs off Mode SVC_32 [<4fe05742>] (remove_free_block+0xe/0x3e) from [<4fe05849>] (block_locate_free+0x7f/0x88) [<4fe05849>] (block_locate_free+0x7f/0x88) from [<4fe0599b>] (tlsf_malloc+0x17/0x32) [<4fe0599b>] (tlsf_malloc+0x17/0x32) from [<4fe0559b>] (malloc+0x13/0x24) [<4fe0559b>] (malloc+0x13/0x24) from [<4fe3a1f3>] (strdup+0x11/0x22) [<4fe3a1f3>] (strdup+0x11/0x22) from [<4fe006f3>] (pr_puts+0x33/0x84) [<4fe006f3>] (pr_puts+0x33/0x84) from [<4fe00803>] (dev_printf+0x6f/0x8c) [<4fe00803>] (dev_printf+0x6f/0x8c) from [<00000000>] (0x0) [<4fe54715>] (unwind_backtrace+0x1/0x60) from [<4fe00de1>] (panic+0x1d/0x34) [<4fe00de1>] (panic+0x1d/0x34) from [<4fe5285d>] (do_exception+0xd/0x10) [<4fe5285d>] (do_exception+0xd/0x10) from [<4fe528bd>] (do_data_abort+0x21/0x2c) [<4fe528bd>] (do_data_abort+0x21/0x2c) from [<4fe524d4>] (do_abort_6+0x48/0x54) ### ERROR ### Please RESET the board ### Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Without this additional step, first read of DWC3_GHWPARAMS* that follows results in assertion of GSTS.CSRTIMEOUT and IP block stuck in a non-functional state. Note that all above has only been observerd on i.MX8MQ (ZII Zest board) for USB1 controller. USB2 doesn't seem to be affected by this.
