From e4f2c9e565b492ac4e008c3f72795e9f7e821662 Mon Sep 17 00:00:00 2001 From: Ahmad Fatoum Date: Thu, 2 Jul 2020 17:25:06 +0200 Subject: sandbox: specify sizeof(dma_addr_t) == sizeof(phys_addr_t) == 8 on 64BIT sizeof(dma_addr_t) == 8 shouldn't introduce any functional change, because we can't have DMA on sandbox. For now it suppresses benign warnings about mismatched pointer and integer sizes when some headers are included. sizeof(phys_addr_t) == 8 was already the case on systems with __x86_64__. As CONFIG_64BIT now is set according to the bitness of the compiler, we can migrate this fully to Kconfig.
