* arm64: Juno/FVP: adjust kernel load addressAndre Przywara2016-01-08-2/+2
| | | | | | | | | | | | | | | | | The default kernel load offset for an arm64 kernel is 0x80000, so U-Boot takes cares of moving the loaded kernel to a matching memory location just before booting it. Since we run with caches off, this takes a while for any decently sized kernel - with no output explaining the reason for the delay (unless one uses a DEBUG build). By adjusting the default load offset for Juno and VFP to be 512K aligned in the first place we can skip this copying and boot much faster. Tested on Juno.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduced in 45b4773 (net/arp: account for ARP delay, avoid duplicate packets on timeout) Check the arp timeout and adjust the timeout start time before the call to eth_recv() so that the sandbox driver has the opportunity to adjust the sandbox timer after the new start time has been recorded. Also, change the adjustment amount by 11 seconds instead of exactly the 10 seconds that the ping timout is expecting since the timeout check is looking for the time elapsed to be greater than but not equal to the specified delay.

Example error: '__of_translate_address: Bad cell count for gpx0' Allowing for that case by modifying the macro 'OF_CHECK_COUNTS', (called from )__of_translate_address(), fixes the issue. Now, this macro doesn't check, that '#size-cells' is greater than 0. This is possible from the specification point of view, but I'm not sure that it doesn't introduce a regression for other configs.

Guard against their usage by hiding the bit mask macros on those processors. These bits are used to prevent glitches when changing clocks on i.MX35 et al. Use the RSTA bit instead for i.MX6 and i.MX7. >From the i.MX6DQ RM: To prevent possible glitch on the card clock, clear the FRC_SDCLK_ON bit when changing clock divisor value(SDCLKFS or DVS in System Control Register) or setting RSTA bit.
