Subject: [PATCH v7 09/10] hw/arm/aspeed_ast27x0: Enable 64-bit EHCI DMA addressing
Date: Mon, 13 Jul 2026 03:27:19 +0000	[thread overview]
Message-ID: <20260713032704.3583103-10-jamin_lin@aspeedtech.com> (raw)
In-Reply-To: <20260713032704.3583103-1-jamin_lin@aspeedtech.com>

AST2700 supports a 64-bit DRAM address space. Therefore, DMA
transactions must be capable of accessing 64-bit addresses.

Enable the "caps-64bit-addr" property for the EHCI controllers
on AST2700 so that USB DMA operations can correctly handle
64-bit memory addresses.
